Feedback Studio known issues as of 2020-11-02

When adding a comment in Turnitin Feedback Studio, you are able to select a highlight color to make comment groupings standout at a glance. Some users have experienced these highlights not displaying as they would expect. Different browsers have presented the issue in different ways and some versions do not show it at all. We are actively investigating this problem.

When submitting to Turnitin, submissions must be 20 words or more to ensure we can successfully generate a Similarity Report. For some Chinese language submissions, this word count is erroneously being flagged as being under 20 words when more have been used. This problem exists for Chinese Traditional and Chinese Simplified submissions.

Workaround: Choosing to 'Accept any File Type' when creating an assignment will ensure that we can accept the file, a Similarity Report will be generated, and the correct word count will be shown.

Turnitin recently updated the servers that send our system emails. System email include welcome emails and digital receipts. Some email clients may experience a short period where they learn to 'trust' that the emails are sent from a legitimate IP address.

Workaround: Email administrators for your institution can manually add our IP addresses to your trusted list. For Microsoft email Exchanges, you can add the IP addresses to the IP Allow List.

Turnitin's email IP addresses

Microsoft files generated using Windows, including .doc, .docx, .xls, .xlsx, .pptx, .ppt, .ppsx, and .pps files, can occasionally fail to process when uploaded to Turnitin. Files created using other operating systems are unaffected.

Workaround: Convert your file to a PDF before attempting to upload it to Turnitin. This ensures it is in a format we can process gracefully and without any problems.

It has been discovered that if an administrator attempts to transfer the administrative account to another user, they will be unable to do so if the email address provided is capitalized. To ensure the successful transfer of the administrator account, please ensure the new email address entered is fully in lower case characters. This does not affect adding instructors or students to an account.

It has been discovered that if a student is enrolled in a class that has discussion boards disabled, they will be unable to view the discussion boards tab for other classes that may have them enabled. We are working on a resolution that will allow students to access their enabled discussion boards.

We have received reports that particularly large bulk submission downloads will produce an empty zip file as opposed to providing one containing the submissions from the assignment. We are currently investigating this issue.

Workaround: If you are experiencing issues with the bulk download feature of an assignment inbox, submission may still be downloaded individually.

Due to security restrictions, if an email address is changed within the Student Information System, it is unable to update within Turnitin’s roster sync to avoid any instances of misuse.

Workaround: If a student’s email address has changed and this needs to be reflected within Turnitin’s roster sync, please raise a ticket with our Customer Support team by emailing

If an instructor were to make a late submission on behalf of a student in the base assignment, the PeerMark assignment will distribute this paper for peer review even if the PeerMark assignment has disallowed late student submissions in the settings. We are currently investigating this issue.

When a student hovers over the (i) icon to view information on their PeerMark assignment, they will be shown all relevant information as well as information from their base assignment. This could include details on resubmissions, late submissions, and similarity score settings which would not apply to their peer reviews.

Administrators may find the instructor tab for their institutional account will freeze and time out if they have high numbers of instructors enrolled. While this is being investigated, if you need to add or remove instructors from your account, please contact our Support team by emailing if you are experiencing this issue.

Students using the Internet Explorer 11 browser will be unable to select the resubmit button and will instead receive an error message.

Workaround: While this error appears when using Internet Explorer 11, other browsers appear to be unaffected. We would ask that students use a different browser to submit to Turnitin while this issue is investigated.

In the event a student has completed more than two peer reviews, some instances have been reported that only the first review is displayed and freezing occurs when the instructor attempts to use the navigation arrows.

Workaround: The freezing isn’t constant. A little perseverance and you should be able to access the reviews while we work on a fix for the cause of the freezing.

Some users have noticed a discrepancy between the submission count found when viewing statistics By Account, By Instructor, and By Class. We are looking at different ways of improving how we gather these statistics to improve their reliability.

Workaround: The statistics are not currently inaccurate; however, the different ways in which we look at the data depending on user choice alters how we count different statistical events. For example, if a class has multiple instructors then we may count submissions multiple times in the By Account view but once in the By Instructor view.

On a small number of papers, the similarity layer can occasionally disappear when loading a different layer. This tends to be caused by the layer not fully loading when the paper has opened.

Until a fix is applied, please be patient when loading Feedback Studio for the first time if you encounter this problem.

When there is a small character count in a submission, it can cause an e-rater to fail to process. Users may see the error 'e-rater cannot process this paper'.

If you encounter this error, please get in touch with our support team using this will help us to diagnose the problem further, and get more data on the lengths of assignments it affects.

Revision Assistant known issues as of 2018-12-19

Currently, the Learning Standards links for Springboard prompts do not show up when users click the link Learning Standards link in the sidebar of each prompt page. Because Springboard uses its own set of prompts and a modified version of Revision Assistant itself, the Learning Standards for Springboard prompts are stored in a separate program and not in the help guides as they are for The Revision Assistant teams are aware of this issue and are working on solutions to store the Springboard Learning Standards in another way.

If a student logs in, navigates to the homepage, and then hits their browser's back button, they are immediately logged out of Revision Assistant. Though students can log right back in, we know this is annoying, so our teams are working on a fix. In the meantime, students should use the navigation links provided in the Revision Assistant headers, rather than the back button on their browser, to move to and away from their homepage.

In Revision Assistant, students are only allowed to join a class from a school in their district. Currently, if a student does try to join a class outside of their district, they are not added to the class, but they also do not see the error messages we created to tell them that. Confusing students is not what Revision Assistant is all about, so we will get those messages showing up for them as soon as possible. In the meantime, teachers, please make sure your students know the class codes they need to join their classes in Revision Assistant.

In a number of cases, Feedback Studio would fail to correctly process a submission causing it to not show when trying to open the document viewer. This lead to the M14:11 error that some users were experiencing.

The M14:11 error denotes a problem with the processing of a submission when it is displayed. Investigation into this issue has been a top priority for our engineers for a number of weeks and we are happy to report that the underlying issues behind this error have now been resolved.

It is possible that the error can still show when there is a genuine problem with a submission. However, for the vast majority of users the document viewer should operate as intended.
