Has anyone ran into the following problem with a Holy Stone 720 4K drone? When the App is not connected to drone from my phone and I manually control the drone through transmitter, it works great. Meaning I can fly it as far as I can see it, and turn and bank(side to side) the drone etc. However, if I connect the app, I can only control turning and banking for about 40 ft high the it just does not respond. I can throttle down, and go forward and back, just no turning or banking it. Have to use the Return to Home feature to get it back.
