Dear TamaraLily
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description, I understand you concern with thumbs up bubbles that appear in Teams meetings.
To troubleshoot this issue, may I know whether you have disable Animation in Teams? If not, you may have a try to do following steps and check if there is any difference:
Go to Settings > Appearance and accessibility > Under Animation, Check Turn off Animation.

This should help you disable the live animation gestures and prevent the thumbs up bubbles from appearing during your meetings.
If the issue still persists, please share the screenshot, so that we can do further check.
Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!
