Android App: Students Unable to Sign In via Google/Classlink (Unknown User Error)

Students encounter an 'Unable to sign in with Google for unknown user' error when attempting to use Google SSO, and 'Unable to sign in with Classlink' when using Classlink SSO. The customer has confirmed the issue is reproducible on her own Android device. Initial troubleshooting steps, including app reinstallation and clearing cache/storage, did not resolve the problem. The error message only displays 'unknown user' without an associated email address. Internal investigation has confirmed this is a bug that will be addressed in the next mobile app update.
