OneDrive Android stuck on "We need to update your account"

Hi, Since a few days ago, I can no longer use OneDrive on my Xiaomi phone.

When I open the app, I get the following message: "We can't display this item. We need to update your account. This operation should only take a few moments." 

When I select OK, nothing happens. 

No sign-in window appears and I can't access any of my files.

I've already tried:

• uninstalling and reinstalling OneDrive
• clearing the app cache and data 
• restarting the phone 
• checking my network connection 

The problem remains. What's strange is that OneDrive seems to remember my account because it opens directly on the "My files" screen instead of asking me to sign in again.

Has anyone else seen this recently on Android? Thanks.
