Answer 1

You need to use release SHA1 fingerprint. You can get it using

keytool -list -v -keystore {keystore_name} -alias {alias_name}

example:

keytool -list -v -keystore C:\Users\MG\Desktop\test.jks -alias test

After that, add it to your firebase project

Setting > SHA certificate fingerprints
