Hi, sometimes I need to fly higher than 120m for a short while. I use two Mini 2 each with Iphone8+. The one with FLY app 1.6.1 doesn't work to adjust to 250m even if I "click" confirm and it shows 250m it "refuse" to go over 120m. The one with 1.5.10 works great. Any suggestion? Can the problem be in the controller?
