Dear Ben Jackson5,
Thanks for posting in Microsoft community.
We test the SharePoint app on our side and we couldn't repro the same scenario.
Please try the following these steps:
- Close all the Office apps.
- Go to iPhone Settings.
- In Settings, tap to select SharePoint app.
- Slide to enable Delete Login Credentials.
- Sign in again and check if the behavior remains.
Thanks for your understanding and cooperation! Have a good day.
Sincerely,
Sean | Microsoft Community Moderator
