King player support - zero help on Candy Royale

It suddenly disappeared from one single device last week in the middle of the Elite challenge over last weekend. It didn't show up again until 2 days ago on Wednesday and then disappeared again. It's now Friday and it's still gone. Someone sent me a link to King player support and all they did is send me a generic email with a link to articles about how events and features come and go. This is crap. This is one device that's misbehaving. It's working perfectly on 5 other devices in our home. The device is brand new, latest android and most recent version of the game. This is a King glitch and they refuse to help their customers.
