So what's the consensus re: dropouts on the latest iOS with the HA-2/SE? I have an iPhone 6, and as I've posted before in this thread, had increasingly disruptive connectivity / audio dropout issues similar to other folks. I thought it may have finally been fixed (for the most part) on iOS 11, but only briefly used it before downgrading back to 10.3.3 due to poor OS performance. 10.3.3 definitely still has these issues -- full dropouts, not just blips.
Also of note, Oppo customer service (awesome btw -- super fast and informative responses), noted this is a documented and widespread issue related to iOS MFi compatibility, which doesn't play nice with higher resolution sources (above 16-bit/48kHz). I can't confirm this being that I use Spotify HQ, which I'm pretty sure doesn't output beyond the standard, but as we've all concluded it's definitely Apple's fault here, and affects more devices than just the HA-2/SE.
