I use several third party apps on my iOS devices, iPhone 8 and iPad Mini 4, for various missions. Mostly mapping and inspection stuff. It seems that no matter what app, no matter what mobile device, firmware version...the video feed never works. The only workaround I've found is sometimes manually triggering the camera from RC buttons can bring the feed back, but it's not reliable. Just really sick of this bug and want to fix it once and for all.
