I have done some testing with updated app 4.19
Landings , take offs , swapping 3 batteries about 8 times.
After swap didnot close and reboot app, not reboot spark and rc and even didnot have to disconnect otg cable.

Each time drone flew more than 50 m far and 30 meters high.

I think the max distance/height bug has been fixed,'.
Now hoping it stays like this and no other bugs popping up

This is great news for all those with mix distance / height issues.  I'm not one of them.

Thanks for sharing, if you encounter any question, please let us know. Hope you have a nice flight.

Thanks for the update!
