I do not have an iPad, so I can not help with that. On the iPhone, I am using the built in music app. Are you streaming the music from a Plex server with the Plexamp, or is it local on the phone?
I do not have the same experience with the camera adapter and BTR5 on my iPhone 8. I just plug it in and it works. Not sure what is causing what you are seeing. Maybe the Fiio rep would have some clues for you.
For Plexamp the music was both local on my iPad, and streamed. I have Plexamp configured for the maximum quality, so no transcoding is happening. I verified no transcoding is happening via the Varys app. It's all Direct Play FLAC.
