Not all players have valid fantasy positions?!

I’m trying to add a player but I am getting an error stating “Not all players have valid fantasy positions in your league”

Just seen someone else talking about this they think it’s an error in the app

Got it, appreciate man I thought I had something wrong with my lineup. Hopefully it’s fixed before Sunday or I’m screwed

Try force closing, opening the app, leaving it open for 30s, then closing and opening again if that doesn't work, then check out the left panel again for settings > latest updates. The fix has been deployed will eventually fully propagate by tonight. If urgent can use web app https://sleeper.app
