Hi everyone, I purchased my Phantom Pro late last year, but with the weather being.. British.. aside from a few test flights whenever the sun was shining, it's been mostly sat in its box waiting for the springtime. So, taken her out of the box yesterday for the first time in months as we're currently staying in a hotel in a really beautiful coastal area, but found I'm getting "NO SIGNAL" on the DJI app on android. She flies fine, but I get no picture preview at all. It's not that she's restricted to a certain distance - the no signal appears from the moment I start things up. I figured it's because I haven't updated the firmware at all since I bought her, and maybe the mobile app updated itself to an incompatible version? So I've upgraded the firmware on controller and the bird, and updated the DJI app, but still the same issue. I'm not sure where to go from here, any suggestions?
