Quick answer
Use Forgot password on the login screen, send the OTP to the registered mobile number, and set a new password. If the number itself is gone, this preview has no way to attach the account to a new number.
Work out why login failed
- The password is wrong. Reset it. Do not create a second account.
- The OTP never arrives. Check the signal and wait 60 seconds.
- The screen says the account does not exist. That number was not registered.
- The account is locked. Wait 30 minutes. Installing the APK again does not clear a lock.
- The app crashes. Check that the file is version 1.0.0 and 2,052,113 bytes.
Checks before you ask anyone else
Confirm the package you installed is app.rs9.come and the label is COME. A different size from the table on the download page is a different article's file. Signing in there will not open this account.
Do not send the password or the OTP to a chat that offers to recover the account. Change the password yourself on the login screen.
Lost number or a second account
The mobile number is the account key in the public login steps. This preview does not publish a support desk that can swap it. Opening another account to "replace" the old one is the duplicate case the login page warns about.
After you are back in
Set a password you have not used on a page that asked you to "verify the APK" by typing it. Then remove the app from any phone you no longer control. Uninstalling does not delete the account.
Questions
Can Download recover an account?
No. Download saves come.apk. It does not sign in.
How long is a lock?
The public login note says 30 minutes. A lock that returns is not an install problem.
Where is the customer-care number?
This preview does not list one. See Support.
