my xbox live on mcpe 1.2.9 on an ios device (and earlier versions of mcpe too) has a problem logging in, when i press sign in it shows the "signing in" screen for a split second and then i'm not signed in and the sign in button is still there, the same happens in the xbox app.
If anyone can help me it would be greatly apreciated.
Wait? Did you just tell me that your using IOS 1.2.9!?!?!? If this is true I believe the problem consists within your device. The device might not be able to support or handle that kind of thing. I do HIGHLY encourage to get a new device or update it to the latest version if you can. There are lots of devises out there that wold work. try IOS 8 and above. Or try to get the ipod 5 or 6.
Ok if minecraft worked before you updated it go online and search for "minecraft pe (version that worked here) ios download" and its when u updated the ios it started behaving like this look up "downgrade ios version".
