Running iOS 9.3.X I've tried signing in and out, but when looking at other players' games, it says 'null' under everyone. Anybody else see this?
I'm on iOS 9.3 as well, and GC seems OK. It's pretty darn slow, but that might just be the office wi-fi. I do get one or two friends showing as "null", but I assume that's because they last played something that doesn't exist on GC. Bit odd if all your friends are doing that, though.
You have to remember that game center as you guys are using it (the old GC app) doesn't exist anymore. The app could be having issues connecting to the sever if they've changed things on the server side. What info do you see when you check GC from inside a game?
Yeah,Gamecentre from within the app takes ages to load,then comes back a 'no games availble' (IOS 9.3).Was fine yesterday. Takes a long while to load within the settings app as well. Can still access gamecentre from within apps though.
