Hello, i'm newbie in this, bear with me. i used Google Play Sign method with Playfab, and it works when i build it as apk. But when i publish it in google play, it doesn't work. I read somewhere that i should use SHA-1 fingerprint generated in google console, and paste in google cloud platform's OAuth credentials. But i used Web applicatino type OAuth, and as far as i know it doesn't have such certficate. what should i do?
