I have passed the Secret Cave 5 TIMES!! There is some sort of glitch that when I try to claim my prizes, it restarts like I've never played before!! Extremely frustrating seeing that I've used a lot of my boosters!!! All for NOTHING!!
I have the same problem! Just brings me back to level 1 when I click "claim prize" as if I never won - so enfuriating, I spent the last 24 hours trying to win it, finally did, and then it's broken!
Yes this is so frustrating. I've won it twice now. I used so many of my boosters the first time round and now they're gone with nothing to show for it.
