Ape Apps

Hello, good evening. I’ve playing this game since last year. My pc broke so I had to use the my phone (iPhone 6) and I tried to put the lowest graphics resolution, no render etc but every time the colony reach a size that won’t allow it to synchronize, it just keep syncing forever. I really want to play but I can’t. The problem is my phone? Or it’s a game bug?
Anyway, just asking, thank you for this awesome game and hope your family is fine.
