I'm on Android and I was trying to rearrange my islands so that the habitats are grouped according to color, but I couldn't get them to move from one island to the other! It was almost like they could only be moved around on the same level. I tried searching the forums and saw people mentioning how hard it is to rearrange from island to island, but no tips on how it was accomplished. If you have any tips I'd appreciate it. Plz and ty!
