A few days ago, I posted the following: "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?" Since then, I've upgraded to version 2.3.8, then down to 2.3.7, all to no avail. I've ensured that all of my Google Play game services information (including license key) is correct. Any suggestions?
