Access Blocked authorisation error 403

[Harriswe]

A user experienced the following problem when attempting to login to the app using a gmail account. Unexpectedly gave an Access blocked authorisation error. More worrying it that the message went onto  say the app doesn't comply with Google's secure browser policy, which is strange since the AppSheet platform is owned by Google. 🤔 Any ideas? The user had previously been able to login without any issues.

Is this AppSheet-related?
