When I try to activate its ability with the card "connect the dots" on the field, the cards it exiles appear spread out horizontally, and the connect the dots card goes off the screen, making it impossible to activate the ability. I lost the game because of this and would like a warranty.

I understand that the range of images displayed in Arena is dependent on the size of the screen. However, as long as the arena is compatible with ISO, I have my doubts about not being able to use it on a regular iPad.
