I’m using Unity 5.5.1 and have the latest google play services plugin for Unity. I have two leaderboards already set up in the google play developer console. Using the normal Social interface to load the leaderboard view doesn’t work. When I try to launch it on the device, it appears as if a window is about to come up for a split second, and then suddenly disappears again with the message “ERROR_NOT_AUTHORIZED” in the logs. However, the interesting part is that the user is authenticated and I am able to load the Achievement view without any problems, so I know for a fact that it’s not an issue related to authentication (at least it doesn’t appear to be). I don’t know how to begin debugging this issue.
Still have not resolved this problem. I’m willing to try any and all ideas at this point.
