New experience logged me out of everything

I wanted to make a new account and when I tried it said I was going into a new experience just for my new account I tried not to do it but I tried it anyway and I didn't like it so I tried to log out and it said relaunch app for new experience and it had a button for that but I just closed the app and reopened it because im not trying to do that and when I opened the app I was logged out of every app and I can't get back in to my main at the very least I tried to after putting In the code it sent me and resetting my password and pressing confirm it didn't work so I reloaded and I was still logged out and I tried again and same result I don't know what to do this app makes everything so stupid and complicated
