I opened my Minecraft app and it said Invalid Session and told me to restart my game. I closed the game, cleared the cache, and when I opened the message was still there. I was told it might be an issue with my game files so I deleted the app entirely and wiped out all my mods and reinstalled the game fresh. I logged into my Xbox account on the new app and still get the invalid session screen and I can't access skins, marketplace, or anything like it.
