I have no experience with the iOS 11.
I am using an iPhone 6 with iOS 10.3.2 and an Oppo HA-2SE and I'm still getting this problem.
I'm using a Peachtree Nova150 at home and an Apogee One at the office.
Both devices are certified by Apple and both have this same same issue continuing even after the 10.2.3 update.
Unacceptable.
I can confirm that after installing iOS 10.3.3 beta 3 on iPhone 6 the problem has been fixed. I am using Oppo HA2 SE. iOS 10.3.3 beta 5 is already available and I will test that soon.
Cable length and airplane mode did not help me. Ironically, I was on an airplane in airplane mode with a long Lightning cable when I was trying it. Same as you, it did nothing, drop outs continued.
I confirm that this issue was fixed in IOS 10.3.3 beta 5. Now I am sitting and listening to my favorite tracks 🙂 Iphone 7+, OPPO HA-2.
Same here :(
Side note - The initial response I got from Oppo seems to suggest they're not confident in a final fix until iOS 11.
@austinguy74 , From my long tests ... I can confirm item 1 and 2.
I am not updating to 10.3.3 final release.
I've got a Dragonfly Red which has experienced problems since 10.3.2. Subsequent updates haven't resolved the issue, including today's upgrade to iOS11 :-(
Just received my brand new oppo ha2-se today, downloaded ios11 to my iphone 7 and connected the two. Have listened to music for 5 hours, at home and gym, no issues at all.
