@BarboraSamkova Although you no longer support the iPad app for iOS 10, it does work well after reinstallation. Thanks!!
Windy works great on the Mac. I can of course download the app on my iPhone (5 SE) and iPad mini (2nd generation). Both devices work on iOS 10.3.1, but if I want to start the app, it immediately jumps back to the background. If you press the home button twice, I see Windy still active, I can get it to the foreground, but the app won't start. Unfortunately.
I hope you can help me.
