New event stuck at 28/28

I’m working through the islands and I’m stuck at 28/28. When I go to the new island it says no battles available yet others in my alliance are past that point. Am I missing something? I’m still pretty new, only level 28. 

 

Thanks. 

You only get 1 chance to do each island right, you probably did some islands twice.

If you get a perfect run you end with 30/30.

You have only one chance to do each island. If you have finish with 28/28 its because you have fail before island 27 or in island 27. The island 27 give the final +2 extra battle to able to do 29 and 30

What’s wrong with videos, I can’t boost anything or get chests?
