When I sign into Xbox live for mcpe 1.2.9 it crashes. I’ve spent over $30 on nice coins and I’ve tried uninstalling the app but this problem still occurs. I’ve tried resetting my iPhone as well but still occurs. I’ve talked to other mcpe players and they said that the same thing happens to them. I thing it has to do with the Xbox live function because if I turn off my wifi I can play on single player worlds but when I turn on my wifi it automatically signs into Xbox live then immediately crashes after. Here is a video for this problem.
