Yesterday I couldn’t remember my Xbox password so I reseted the password leading to all of my accounts connected to my Xbox Email disconnected. I went on Minecraft disconnected to my xbox but I stop freezing but then when I signed up my Minecraft frozed, so I reseted MCPE and still it was frozen. -Harry
