What's going on here; is this true?  See last segment of the video called Final Thoughts:
If you fly the drone in a dark environment and you lose GPS, the drone will automatically switch into acro mode; huh?

At 21.50 he flys through a tunnel and looses GPS,  and then crashes as he didnt correct for being in Acro mode, the issue is he wasnt waned of the change.

The GPS to ACRO issue in dark spaces WITHOUT warning needs to be fixed in the very next firmware update.  This could definitely cause issues for first responders who need to fly into a dark space and NOT get a warning on the GPS to ACRO mode switch.  

Hello, Everyone!

I was flying in a room in the evening with a fairly strong light, but it was still not enough for the drone's sensor. Suddenly it sped up bounced off the monitor and hit the curtain. Good thing it didn't hit the wall. Too bad, it looked like it was possible to fly indoors, but it's better not to. Maybe changes in firmware will help something, for now you have to be very careful. Maybe on a full manual with Controller 3 it will be easier

Hi there, The Saint. Thank you for bringing this out. I will forward this to the relevant team to check. I will keep you posted. We appreciate your patience.

The day I got it flew into a low light room and the drone completely lost control and didn’t even hover. Crashed, propeller snapped and my heart too.

Hi there. During the flight, an aircraft only loses its GPS signal if it's subject to interference or gets close to buildings, and from compass disturbances. This is quite rare. Also, the screen of the Goggles 3 should show a weak GPS signal warning.
