Hi @Anonymous
Is this an issue with using the same link for multiple meetings or something that can be fixed?
I am not sure what is your meaning of using the same link, do you mean you rejoin the same meeting but cannot use Q&A and post new questions?
If so, we recommend you try to login to Teams web client and join this meeting to see if you could post new questions in Q&A. I did a test in my environment, and it seems no issue.
