I've been having this issue recently, and I have no idea why. My Google Play game services are set up properly, or at least according to the tutorials that I've followed - however, none of them dealt specifically with apps exported from Buildbox. Every time I load up the project in Android Studio (or even a published version), the leaderboard shows up, as if it's loading, and then quickly closes itself. Is there something that I may be missing?
Using Buildbox 2? If so you may need the Android Updates in 2.2.8 to resolve this: https://www.buildbox.com/forum/index.php?threads/buildbox-2-3-8-2509-beta.17155/
