Anybody on Tahoe 26.1 having very laggy Microsoft Teams performance? At times, it doesn't even open and I have to reboot. I already did an uninstall/reinstall of Teams twice

Thanks
 
Desktop or browser based?

If it's desktop based, Microsoft did something recently which broke it on windows as well. It's equally horrible on both platforms. Had to resort to using WhatsApp a couple of times recently instead.
 
Many Microsoft mobile apps have somewhat broken for last few months - and not only on Mac. Outlook on Android lost functionality of all swipe actions.

Teams has lost date and time format settings which did work before. Now this part of settings looks absurd (and no - "follow OS settings" does not work either).

It has been like this for at least a month or even two.
 
Other than the standard Microsoft overly-convoluted interface and overstuffing of features that never work as a normal person would assume, it's been working fine for me.
 
I have the Office365 Teams app on my MacBook Pro and it's been fine on 26.0.1 and 26.1

Maybe try uninstalling it completely with AppCleaner app (use it all the time), then reinstall fresh from the App Store.
