8.4.1 is Digitally Signed by apple, but for how long, who knows
Once you install OS9 and Apple stops signing 8,4.1 then your SOL

What are the issues with iOS9? I'm on it with no issues on my iPad Mini 3 and iPhone 6.

A number of reports of lagging, loss of signal, reduced range on IOS 9. Many seem to find that the problems disappear when they move back to 8.4.1.

A DJI representative claimed on this forum there are problems with IOS 9 and recommended not upgrading at this time.

I saw my video feed break up quite a bit on my IPad Mini 2 so I'm back to 8.4.1

Thankfully, I am not experiencing any of the talked about, negative affects, subsequent the new iOS9.
Everything is still running clean, smooth, and incredibly fun for me.
So glad I don't have any of those major concerns. It's been golden, just like the P3 Pro model stripes. ;-)

I flew yesterday for the first time on iOS 9.  Using my iPhone 6, video broke up often, POI only worked once then wouldn't activate anymore until restarting the app, and the app crashed a number of times.

I'm also not sure if it was due to ios9 but I noticed the the P3 drifting a bunch and didn't seem as easy to control.  Nothing changed since my last flight other then I was on ios8.  It could have just been windy, but it didn't seem any more then usual.

Reverted back to previous iOS 8.4.1, reinstalled the Go App, first test flights this morning using an iPad Mini 2 were perfect.  Weather 73 degrees.  I'm not writing video to iPad Mini 2, I don't need it and it probably requires CPU or GPU time.  
Yesterday, using iOS 9 I had the following problems 1. video locked up  2. video cut off  3. incredibly poor redraw on iPhone 6 and iPad Mini 2.

Ranges?

If you are asking about distance?

For me on my iP6+ on ios 8.4.1 running DJI App 2.3.0 ( have not updated to the newest ), I have gone 2.2 miles ( that was enough for me ) with a windsurfer antenna with 3-4 bars and not losing signal

Hope this helps
