You'll needto change the settings on your account and you can do so by following the steps here: help.minecraft.net/hc/en-us/… If you continue to have issues after that let me know. ^TK

Already done that. I am having this issue with all accounts on my Xbox, leading me to believe that it's possibly a software or console problem rather than an account problem. This problem does not occur using the same account MCPE, only on Xbox.
