Can't access Realms

Cant access my Realm since new update. When I'm able to join the realm, it's not long until it starts bugging out (not loading chunks, not loading animations). My internet connection was a little unstable yesterday, but now it's fine and the problems persist. It says I can't access my realms at all because of how my account is configured, but I haven't touched the settings. Uninstalled and reinstalled the app, still the same problem. It's been about 12 hours since I was last able to join the game.
