When every I try and unlock a season reward I get an error messsage saying “The tier reward unlock failed, please try again later” I’m new to MCC and have only being playing for a couple days so I have no idea if this is an on going thing but if there’s anything that could help resolve this it would be nice already tried a couple things like Verifying the integraty of the game, Restarting computer and WiFi and uninstalling and re-installing the game.
