Ive been having the same exact issue on range...flying in congested area...and get repeatable differences with the mini (range at 3,500ft) before signal breakup most times 3,700ft for RTH....New
Air 2 = 2,200 ft before complete signal loss and RTH......something is up for sure....firmware is up to date....both in Auto transmition mode and flight path is the same. Pretty disappointed that its worse than the mini.
Side note, ive read that folks in Europe only got like 700 meters out of theirs...which is close to mine and others in this thread that have had issues. The ADS writing is a sticker that looks to be slapped on wonky on the prop arm. Im wondering if they were in a rush and just put a sticker on international versions and gave folks the non ADS models due to time/limited production. A stretch but id figure the lettering on the prop arm for "
MAVIC Air 2" (which looks to be painted on) and "ADS" would be matching. Also had a $0.42 cent credit on my acct when purchasing refresh care (not sure where that came from....was it an ADS sticker discount?)

just kidding
Another thought is that the ads was not enabled in the app by default and I wonder if it limits the range automatically if its not enabled (for 1st flight etc)....The signal drops off almost instantly at 2,200 ft +/- which totally does not do that on the mini (it looses signal gets pix-elated more and goes a few more hundred ft). I may try to reinstall app enable ADS before flight and see if that helps. Next would be a call to DJI.
Any thoughts on solution would be helpful. The mini outdoing the
air 2 so badly on range just hurts
