I to am having the same problem. I received a quest for an event at "the Beverly" which I can not find but the quest disappeared along with the three other goals that I had know I am only doing dates trying to reach the 1000 follower mark and see what happens then.
Same thing happened to me. I downloaded the link, played to level 8 and received a notification that I would have the clothes I just had to go back to KKH and Simon would call. Went back to game no phone call. I believe it is a glitch. Plying on a Android Samsung galaxy 4
