COMEA COME update failed but the old app still works
If an update fails while the existing COME app still opens, preserve that working state and diagnose the update separately.
Record both outcomes
Note the update error and the installed version that remains. Do not describe the whole app as unusable when only the replacement attempt failed. This distinction helps avoid unnecessary data-clearing or reinstallation.
Check the file and device
Confirm transfer completion, current source, available storage and any stated requirements. An update can fail at several checks; a generic error does not identify the cause by itself.
Avoid destructive shortcuts
Do not remove the working app, disable protection or use a modified file to force installation. Keep account recovery available and ask about the specific update issue through the service's displayed help route.
A useful next step
Continue using the stable installation where appropriate while resolving the update condition through a traceable route.
