Teams App endless login loop on Android Phone

I have two instances of teams app on my android phone. One instance if for my personal account (uses personal email address), the second is for a work account (uses work email address). 

The teams app instance for both my personal and work account asks me to login to my account on an endless loop, making both instances of the app unusable.

These are the steps I've tried: uninstalling and reinstalling teams instance, and clearing cache for teams app from phone settings.

I saw in another post that its recommended to delete the authenticator app. This is not an option for me as I have many accounts setup in my authenticator app that I dont want to lose.

Any suggestions on how I can end the login loop would be recieved gratefully.
