Unable to Join league

Hello, I finished my TODO List, but I am still unable to join a league. Does anyone know how to fix this?
YOu should have gotten a notification when you've reached lvl 5 journey mode?
Same thing on my end, this was what actually made me quit playing a year ago. Thought in a years time it would have been fixed......
I forgot what I did, but I fixed it almost two minutes after of posting this LOL
