G-suite user account syncing issue

[Mrpower]

I have a staff member using an iPad and Google device policy app to sync their account to the g-suite. I have install the profile on the iPad, it syncs fine, then within a day or two the sync stops and the user can't access their drives or documents.

I updated the iPad this morning to iOS 13 and made sure everything is up to date.

This is the second time I have had to delete the profile and reinstall it to restore syncing. Does anyone have any ideas of what the issue might be with the syncing and why after a few days it stops syncing?
