RE: Wind field vs vector and wave forecast
Thanks for your detailed answer, helps a lot. It is good to see that the information is implemented in the UI but is just not visible for me.
I am using iOS 12.1.2 with Windy.com v. 17.05 with an iPhone 5s. My App Store and settings tell me both the App and the OS are updated to their latest versions.
