Answer 1

When you upload an app to the play store then the play store creates a new certificate called "App signing certificate". This will contain the SHA1 certificate that you require. It can be found at:

Select App -> Under Release -> Setup -> App Sigining on your play console. Copy SHA1 and paste it in your Go to Console -> Select Project -> Project Settings -> Under General Tab -> Under Your Apps -> Select App -> Add SHA1 fingerprint.
