Unity3d Game Center login issue

Hi Apple Devs,


I'm making a racing game with Unity3d, and it uses Game Center for leaderboards and achievements. I previously used a plugin called iOS Native for this, and it worked just fine until I updated the plugin. After that, it stopped logging me in to Game Center, but there was no debug info in Xcode at all, not even an error. At first, I thought it was the plugin, so I tried Unity's Social API. I got the same result as before. I tried pretty much everything from updating Unity to starting a fresh build. Nothing has worked so far.


I've asked about this on both Unity Answers and Unity Forums, but never got an answer, so now I'm asking on here since the issue could be Apple-related. Any help would be much appreciated!


Thanks

Jake
