iOS version 14.2 with DroneDeploy version 4.29
Linear app would not resolve from the standard lawnmower pattern to the Linear Flight pattern and stay. Interface was active and changes in the Linear section were taking affect, but as soon as I hit the checklist the flight plan went back to the lawnmower pattern. Attempted to restart everything including the app twice with no resolution. I attempted to let it start anyways just to see which plan it chose to actually fly and it did try to fly the lawnmower pattern so I stopped it an used Litchi.
