I’m on an iPhone XR and I’ve never been able to get it to work properly. Every time I set it up and adjust the size and position it readjusts itself with the button half off the right side of the screen. I’ve tried using this method several times. I don’t understand why it doesn’t work as intended. You’re right. It doesn’t cover half of the right side of the screen when trying to use it. Also, it frustrates me that when I can get it to work (by pressing exactly where the button is supposed to be) I can’t use the fishing pole properly using this method. I do a slight tap to cast my line and it goes in the water, but when trying to activate a long cast, it never, ever works. I’m glad you’ve chimed in about your issues with this control scheme. Thanks.
