Ok, the solution here is
1.) Remove and re-add the mobile app and see if it works
2.) Android 10 is the latest version but if you can, see if there are additional updates
3.) If it doesn't, raise a ticket via the Microsoft 365 portal. I have raised a bug reference for you here (
https://microsoftteams.uservoice.com/forums/555103-public/suggestions/40897678-zooming-issue-on-reco...) send the screenshots, reference this bug and provide all information so far
Since the issue is impacting only you and no other android devices it sounds like it may be device specific, however the solution for this one would be to raise a ticket and to get that confirmed. It would be good after the investigation, if you could feed back here that it was the case
Best, Chris
