Hello, I have a question:
Last weekend, I startet in a narrow valley with no GPS-signal, so I took off in ATTI mode.
I had set maximum flight altitude to 500 m but far below I got the message: maximum flight altitude reached. Then GPS started to work and in GPS mode the AC could ascent to 500 m. Is this a normal behaviour?

Greetings

Height is restricted to 26 feet (8 meters) when there is no GPS signal and Vision Positioning
is activated.
Height is restricted to 98 feet (30 meters) when there is no GPS signal and VPS is inactivated

Thanks Labroides,
30 meters then, because P3S has no VPS

The P3S has no VPS. I didn´t try it in ATTI mode,but i think Labroides is right.

Have you tried to re-install the APP? If no helps, please tell us your DJI account, flight time and sync the flight records, I'd like to look into it.
