I have it on my android. You may need to update your game. 335 battles in 38 days is a hair under 9 wins a day. It requires more gems to continue the streak too. So I have found the colosseum useful as a reference rather than the battle area. Since we are getting so many new elements, and we need to hatch so many I find it harder to keep track of them as my forest grows. Plus I play on IOS and android, and I can;t remember which account has one which ones. So I'm trying to raise my new elements and I try them out in the colosseum. I don't ever expect to win one so it makes it fun rather than a chore.
