Game Center/Google Play stopped connecting
Not sure what changed to break it, but previously I was able to log into Game Center fine when launching an iOS game, and now I can't. I've tried this with multiple projects, including Tappy Chicken, on both a PC and a Mac, in both 4.10 and 4.11. Game Center will never connect. The "Show external login UI" node always returns a failure. I pulled the full version of my project from iTunes using TestFlight, and Game Center was also failing in that. I tried downloading the full version of Tappy Chicken from the App Store, and Game Center worked in it. It's only failing in projects that I either launch or package from UE4 myself.
-Edit- Android seems to be doing the same thing with Google Play, again not limited to a single project. Also interesting is that banner ads are working fine.
