Issues after Cross Progression is activated on your account? Check here first!

I got the promp an hour ago and went through and received all my cosmetics. However now my UI is bugged and I can't click on my stats nor can I join any games except orientation matches. When I restart my game I am able to see the normal game modes but I cannot ready up or join my friends lobby as it is stuck on 'party not ready'. I am frustrated and upset, please help.
