It keeps reloading every email, so it is all synced with the server, but when i close the app, or when i turn off the phone and go back to the mail app, then it just starts all over again, it removes all the messages from the phone and starts reloading them all.

Kept all settings bone stock and im not using 2fa.

Changed back to a different mail provider and the problem dissapeared.

Contacted support through chat but was given a link to the apple site and that was that.

This is not really giving me much confidence in switching over from Gmail workspace.
