That’s really interesting as I have always assumed it was FW as it appeared to start shortly afterwards. The go app could of course been updated at around the same time confusing the source of the problemI don’t believe it’s a firmware issue. I think it’s an app issue with iOS devices. Or in other words the dji go app for iOS has issues. I didn’t have problems until I updated to the 3.1.15 iOS go app. That and my android device works perfectly fine with the newer firmware. Bugs in the iOS app seem to be the root of the problem.I have made developers aware of the problem.
