I completed all 15 challenges including the secret cave missions from the mcc 15 event. i received the cape reward pop up screen, however, i have yet to receive the cape. its been nearly 2 days since completion. the event is now ended and i cannot join the event to figure this out.

I have also tried recompleting a minigame (when it was still available) and my game has been rebooted many times.

i even bought the apple store app to try and launch it on mobile, but that hasn't worked either??
