So just got my phantom 3 advanced. Went through all the set up but when dji app is opened it says 'disconnected' at the top. So I guess this means FireWare in remote control needs to be upgraded. When I go to the file to download on the dji site and click on it, I get a message saying Safari can't download this!! My 2 sons were really looking forward to flying over the long weekend, any advise, thanks in advance.
