I haven't been active on Minecraft PE in a while, however I did have the game downloaded. When I tried opening it, it gave me an option to sign in. However, when I try to sign in with my Microsoft information (which is all correct) it says "Sorry, something went wrong. Give it another try, or try on Xbox.com". I've tried uninstalling and reinstalling both my minecraft game and xbox app. As well as updating and securing my Microsoft account. I've also researched other cases, but I have not seen any solution. If anyone has a solution, please respond to this report.
