Ever since I updated the Go4 app for my P4Pro, I get into a flight, start taking photos, and then the image freezes with the buffering circle around the shutter button continuously cycling. I have to shutdown my iPad 2 Mini and restart it to get out of the lockup. I have 7 GB of free space and the latest iOS update. My bird has the latest firmware update too. But this didn’t start until the latest app update. Any suggestions???
