Hi all, just started using iPhone to fly p3a and noticed that I can't change from auto to custom channels in the hd channel screen, the custom button is greyed out.
Is this normal on iOS device ( have been using android up until now but video lag too bad).
All my firmware and software are up to date.
Thanks

It's normal if you live in Europe. You can make this option available if you change the Region of your device to U.S.A.  For most it's probably best to stay in auto mode and let the system switch channels if one starts to get noisy.

Is the problem at all locations.Best advice already given.I run android and its always greyed out and works perfectly.
