Students unable to submit during the late period

[nlitnme]

I have two classes running right now that do not allow students to submit during the "late" period. For example, one deadline was 12 Sep at 23:59, with an ability to submit with a penalty until 15 Sep at 23:59. However, since 12 Sep at 23:59 students have been unable to submit. I have multiple screenshots from students verifying this, and I just had a student show me her screen. Instead, when they click "submit" a screen appears that says "Cannot Upload Submission." 

The submission requires pdf only, and students are trying to submit pdf files.

I have been through all the related threads and watched videos on this to confirm my settings are correct.

In one class I have a setting that has an opening "Available from" date and time, and in this one I do not, to see if that would make a difference and it does not.

Anyone have an answer?

The answer is not in the Canvas settings, but the Turnitin Assignment Inbox settings:

I'm sorry to hear about the issue you're facing with the submission system in your classes. It seems that despite the extended deadline, students are unable to submit their PDF files and instead encounter an error message. You've already checked your settings and reviewed related threads and videos, but haven't found a solution yet. It would be best to reach out to the technical support team or the platform administrators for assistance in resolving this issue. They should be able to provide you with a more specific answer and guide you through the troubleshooting process.
