I'm having some trouble getting the clientId to configure correctly for use of IAP and Google Play Games leaderboards & achievements in a game I'm ready to launch.
If someone here has experience working with Google Developer Console, and has roped this problem, please be a friend!
I've got the game to login to Google Play Services, but I accidentally deleted that keytool, now using another, but won't login or show achievements. I may have to pay an expert. Let me know if that is you.
