go doesnt work when both controller and aircraft are on when go is also on

I have the latest updates ( 1.10.50 ) and work fine.

Just the go app....I have it working ok on android

any help is appeciated

Mine crashed on my Android- I have the latest Firmware, but crashed during flights.

My 6 is having issues too, posted about it:

I use the iPad Air 2 and after all updates in firmware to my i1 and DJI Go update to .22 the bird is flying better and further than ever, last weekend was perfect, no wind clear skies and in the high 70s. What a difference from flying in mid summer heat, where 3500' with wind surfers meant broken video feed, I made it past that mark with maybe a couple of momentary freezes. Really happy. However, I had the bright idea pf doing the litchi fpv trick tonight and to my disappointment find that in both litchi and DJI Go, the video feed does the same scan I got when I erroneously used an iPad 2 and it couldn't handle the app.
Does this mean that my iPhone 6 is now obsolete and if I want to fly Litchi fpv I need to upgrade my phone?
tear dripping down to the floor in slo mo!

Please update it in your original post and we can follow your case easier.

What order are you firing things up?

When I first started flying my I2 I was using my iPhone 6 without any problems. That was 8 months ago. I switched to an iPad mini-2 (A6 chip, I think) rather quickly and finally to the iPad Pro 10.5inch (A10X chip).  
Processor speed is everything when running apps. An on-line comparison of iPhone models shows the iPhone 6s to have the A9 chip so maybe the iPhone 6 has the A8 chip (??).  I'm sorta guessing, but as the software for these drones gets more and more complicated faster processors are a good idea.

iPad 7.9" has the A8 chip; iPad 9.7" has the A9 chip; and both iPad Pros have the A10X chip.

The answer may be as simple as deleting the app and re-installing it since the iPhone 6 is not "old" by any means, but maybe it's time for a faster chip.

Try deleting GO and ALL its folders from your device. Restart and re download a "fresh" copy.
