COMEA COME login failure after updating is a separate check
If COME opens after an update but sign-in fails, record the login message separately from the installation result. Repeating the download may not help.
Confirm what succeeded
Check whether Android completed the update and the app opens normally. Then identify the sign-in symptom: rejected credentials, recovery trouble, missing verification message or a connection error. Timing alone does not prove the update caused the account problem.
Use the matching help
The Forgot Password topic points to recovery on the login page. Use the current recovery process when credentials are the issue. If the screen reports a network failure, check connectivity before changing account details.
Preserve useful access
Keep any working session and recovery method available. Do not clear data, uninstall or create another account as the first response. Never share passwords or OTPs in a technical report.
A useful next step
Follow the current service's account-help route with the exact sign-in symptom and a separate note about the update result.
