Thanks in advance for any help y'all. Just bought a mavic pro used. Everything seems good with the drone, but I can't fly it further than 1100 m. without it losing RC signal or the picture getting blurry or getting dropped all together. The drone frequently says it "hit an obstacle' even when it's 100 m in the air and not close to any obstacle. I tried flying in a philly suburb (thus I understood why it wouldn't go far), but then took it to a beach town with no tall buildings and the best I could get was 1100 m. Not even a mile without issues. Anyone have this problem? Any advice? Thanks everyone! Beginner mode turned off, btw

Sorry for this trouble. Please make sure that you disable the maximum distance on your DJI Go 4 app. Then pls try to fly it again and let us know the difference. Thank you.

OA suddenly stopping the drone is due to a heavy amount of light hitting the front sensors - turn away from the sun or switch off OA.

Agree with Andy, turn that off and try again
