I did a flight with the new iOS app with iPad Air and all was good, no issues. 2nd flight with new android on my nexus 7'and lost connection within 150 feet.
Newbie to drones, and have no experience with any other version of the go app. the only things/errors i have seen in my very short time with a p3s is compass stuck and strong interference. no issues at all during flight in beginner mode.
