further to my comments in post #92 what was conspicuously missing was the detailed information which should normally be included when discussing stuff... my apology in this regard.
app 3.1.18
aircraft 1.11.01.50+
r/c 1.7.80
camera 1.10.1.40
The above are the versions which were running in early September. I was having the height/distance issue and chose to delete the app on my ipad air and reinstall it... I mentioned I would come back and report my findings and I'm happy to say everything seems to be back to normal at least for now.
Some have reported when they made the change... deleted/reinstalled just the app that the issue returned a number of days later. this hasn't happened to me as yet... I'm hoping things will stay normal until the next round of firmware or software updates. Yes I know thoroughly optimistic!
I fly and practice a lot. I have 9 batteries and generally fly several of the batteries down and have not seen the height/distance limitations since reinstalling the app on each of my days flying. When I land on a depleted battery I just set the r/c down leaving it powered up, go over to the drone, shut the battery down, remove and install a freshly charged battery, turn it on, walk back to the r/c, wait a minute until everything is recognized, do a flight check and start flying... been doing it since earlier Sept. when I notice the issue....
so for some I'd say delete the app on your device first... it's a pretty quick deal compared to some other possible solutions... if it doesn't work obviously you're going to have to put more time and energy in resolving your issue.
Fly Safe and of course have fun doing it...
