We are trying to release Google Sign In in android app. Then we tested the app in using debug keystore it works fine. But when trying to release to production we were adding release SHA1 here but unable to add with following error:
The SHA-1 you specified is already used with the same package name for a different Android OAuth2 client.
But it create Android Key & WebClient but not AndroidClient.
But We are sure that there we have deleted all the ClientIDs in all three accounts and tried adding it. But same error. Checked all the projects multiple times but in vain.
Also checked all the questions on SO but no solution. Please help.
