Yoser, I'm very green, maybe 20 minutes of flying with my P3A.  I'm tring to increase the altitude and distance limlits but the app won't let me.  I'm not on the beginner mode and have the enable max distance slide button disabled.  I've flown the aircraft and seems to handle well but I cannot get out the limited area.  I did struggle with the firmware updates when I first got the drone but all seems normal when flying, compass, gps, etc.
Any ideas, tka a lot in advance.

I deleted the go app and re-installed it and now I can make the changes and they seem to stick.  Will find out tomorrow when I fly.  Try and keep you posted.

It's not hard, you'll work it out.

Clue ... the settings are stored in the Phantom and not the app.
You have to have the Phantom connected to make changes.

But I make the changes using the app when  it's "connected" to the p3a.
