Apple has xtopped signning iOS 10.3.3. You who have problem with ios 11 cannot goback. The only way to get ios 10.3.3 is to purchase new i7 and below.

Apple is not allowing you to revert back to a previous version.  Try iTunes, which is what i've used in the past.  Secondly i've had zero issues with IOS 11 even during my beta testing period

You cannot goback to 10.3.3 even via iTunes. Though you get the ipsw and try to restore but it won't work because iTune will fail when it signs with Apple. Most user do not have problem with DJI Go but some of them does. I myself have issue with DJI Go on iPhone 6+ with ios 11 but not on iPhone 6s+.

No problems on iOS 11

No issues on iOS 11 with iPhone7 +, what is your issue with DJI GO on iPhone 6 + with iOS 11? Could you please provide more details?

For me, the DJI Go 3.1.15 crashes with ios 11 on 6+. But I do not have the issue with 6s+ or 7+. I saw some other in this and other forum have issue with DJI Go 4 4.1.11/12 with ios 11.0.2. Previously we can rollback to 10.3.3 which we don't have the issue but now we can no longer rollback.
This is just FYI for those who want to goback to stable environment. Now, those who have issues with ios 11 have to wait for new release of DJI Go/Go 4.
