Cannot log into Microsoft account on mobile data, which also due to another bug I presume, makes it so that I can't go into settings or load any worlds, even if they are singleplayer if I'm actively trying to login to my Microsoft account at the same time. Yes I've tried offline mode too with airplane mode and that doesn't work for some reason either.
The 2 screenshots I've provided is what happens when I try to go into the marketplace and load a world respectively
