I've noticed that every time I want to unlock a "blue" zone I have to clear out all by browsing history off my computer to allow the "pins" to show up to click on. If I don't there will be no pins to choose from however all the airspace information is still showing up just again no way to choose the airport. Whats also weird is that as soon as I clear the history choose a airport and immediately attempt to choose another one same thing happens so I have to clear history again. What am I doing wrong? How can I fix so I don't have to do this all the time? THANKS
