Hey everyone, I need some help with my DJI Mavic Pro alpine white edition.I flew the drone outside very easily and it works great with GPS, so I decided to try it inside because it says you can and I've seen many people do it with the vision positioning system.  But, when I tried to do it inside, it went to atti mode.  It wouldn't go in OPTI mode when it was sitting on the floor.  But, if I pick up the drone off the ground about 1 foot, it says OPTI mode.  As soon as I put it back on the ground, it says ATTI again.  I'm not sure what to do.
Thanks.

Hi, thanks for reaching DJI Forum. We do apologize for the troubles. Have you tried to move to a different part of the house/ floor? It has an indication that there is an interference inside your house. There is a high risk of crashing the drone when you do this so please fly with caution. Thank you.

DJI Gamora, I tried in my garage, and then in my downstairs inside my house.  Both places stayed in atti mode on the floor/ground.  Would I need to calibrate the compass?  I haven't done that yet.

I just got the drone yesterday and I haven't calibrated the compass because it didn't tell me to.  Maybe that's the issue?
