I posted my friend code but have maxed friends and I keep getting notifications which doesn't allow me to pick anything up or play!
Same problem, looking forward to a reply with a solution...
You could just remove some friends and open the space up
You can change your Friend code by clicking the refresh button next to your existing code.
@Cram21 It no longer gives me the option to change codes!
edit: nvm, it worked this time! Thank you :)
