Supposedly the iOS app on IOS 10.x.x supports 4 Garmin Virb X/XE cameras. I'm only able to get 3 to show up and the last (4th camera is the iPhone iPad) camera which is disabled by default when using external cameras).
With the 4 cameras found, I try to connect them and the iOS app crashes. When only selecting 3 of the action cameras (4th turned off) it connects correctly, but still leaves the iPhone/Pad camera in the 4th slot, which would be nice to have my 4th garmin camera.
is there an iOS beta app I can try?
