I reported this very issue a couple of weeks ago. I dont get half, I get about 15% of wind at the top. Renders the app pretty useless.

Bug with wind only showing top 15% of screen. I am using iPad Pro. Was working ok but now only shows the top 15% of the screen with wind. If I zoom in the wind does as well but only the top 15 %. Works fine on my iphone but not iPad. Help!
