Analytics and activity reports that help educators track student engagement and performance
Hello Salma,
Good day! Thank you for posting to the Microsoft Community.
Thank you for offering more clarification on this issue. I can see that the reading Tab is greyed out, hence it cannot be clicked.
Are you getting the same behavior on Teams web client and within different browsers Incognito/ InPrivate windows?
If the issue is occurring on Teams web, then there might be a configuration/ permission issue for that particular class, I highly recommend contacting Microsoft technical support team.
Microsoft's back-end support team can inspect the advanced logs and investigate the cause of this issue from the back end.
Due to the limited permissions and access resources of our community moderators, and the privacy of your data, we are unable to collect certain types of logs in public forums.
