Did you try deleting the app and re-installing?

How to open MS Word? Running an iPad with iOS 16. I have no issue opening MS Excel but cannot open MS Word as it loops back to prompt entry of my email address each time I enter my password. (The email is linked to my personal O365 subscription, I also have a work account). Same result if I select to sign in via the Authenticator app - loops back to prompt email entry.
