Android google login consent screen not showing private policy and login error

[jerryannie82]

consent screen is different in debug mode and release mode.

In debug mode all is fine.

But in release mode (download from google store), private policy is not shown in the consent screen.

And google login shows error.

Is there any idea to fix this problem?
