I would not consider this resolved. I can not play a multiplayer games like I could 4 days ago. I can not sign in to xbox live. I bought this game to play with my daughter and I can not. Everything worked fine 4 days ago I did not change anything so why doesn't it work now? If signing into xbox live shuts down minecraft pe is this a mojang issue or xbox live issue?
I am having the same issue.
Same issue for me v1.0.4 on iPad air 2 iOS 10.2
