Sometimes sending the drone up as high as possible and as quickly as possible will at least keep above everything it might hit. And this usually stops the toilet bowling. Also sending it horizontally as fast as possible also works.
I just found that holding both sticks straight down for a second will stop it from toilet bowling as well. And if you do that a couple times it will re locate itself
Just watched your video and found it very interesting I don't have a dji yet. But I'm working on it But I do have a hs 720r. That is having this problem. I'm think about taking it apart and looking for areas that can be causing interference with the GPS signal
