A new meeting on the iPad app seems to last about a second before exiting the meeting for me. I did not seem to have that issue on my Linux machine. I assume this is something that will be resolved with a software update. Does anybody think I'm doing something incorrectly?
See if you can update it. If not, try uninstalling and reinstalling the app.
Teams is officially supported on the last two IoS/IPadOS so that's IPadOS 13/14, but elsewhere in the official literature specifies that IoS 11+. Some features like background blur need a minimum of IoS12.
