Solve the error you can observe. Reinstalling immediately can erase useful local information without fixing an account issue.
STEP 01
Locate the failure
Distinguish a screen that will not load from a rejected password or delayed OTP. Write the exact error message before retrying.
STEP 02
Check the basics
Confirm connectivity, the registered phone or email, and any publisher service-status notice. Avoid repeatedly requesting codes, which can trigger limits.
STEP 03
Use genuine recovery
Open recovery inside the trusted app or publisher site. Support should not need you to send an OTP or password through a public message.
STEP 04
Escalate with a concise report
Provide the app name, Android version, network type, and the point where the error appears. Redact personal details from screenshots.
