Very simple. Every time I toggle off the webcams preview, the airport data for weather (temps, wind, etc) is also toggled off. Even more, when I try to toggle on again the airports, not only the webcam preview is also toggled on but the data from the airports do not appear anymore. I have to refresh the website to view back again the airport data.
My guess for this bug is that the toggle button for airports and webcam preview are in the same position and the UI was coded in a way that the button is recognized by its position, rather than by what it does.
