The mobile game does not allow me to check out the islands number 7, 8 and 9. And the dragons that are in them become inaccessible for contact (the game closes when I select "find" in the dragon book. I would like you to resolve this issue by revealing all the islands at once, allowing each user to decide which one to display.

@maicon-lopes You have to ask the support for help with this issue. Click the gear at the upper right side of the game screen and then support at the bottom right. Then find a section to put your problem.
