Tools that support reading fluency and comprehension through guided practice and feedback
Dear David,
Good day!!
I understand your concern and I would like to convey that I have tested the behavior at my end with the Reading Progress assignment in the Class Team, where the students in the Class are able to turn in the assignment without any issue.
In this situation, I would like to confirm whether you are able to turn-in the Reading Progress assignments in the Class Team when you access it via InPrivate or Incognito window of the browser.
If the same problem happens, I am sorry to convey that the problems should be further investigated by the related development team, where they can collect the related logs while reproducing the problem and perform further investigation.
Note: I have also checked the service health dashboard at the Microsoft end, where there is no related incident found.
So, I request you to connect with your IT admin of your organization (How do I find my Microsoft 365 admin? - Microsoft Support) and raise a new service request from the Microsoft 365 admin center so that the related development team will connect with you and investigate the issue further.
Reference: Get support - Microsoft 365 admin | Microsoft Learn
Note: We apologize for redirecting you to related development support team because the moderators in this community are limited with the resource for further investigation and to get a quick resolution to your problem, we requested it.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
