So if I'm reading this correctly the issue is with the Aurender interfacing with IOS 11.
To summarise,
1. there are issues with updates in general
2. there are specific issues with Esoteric N-05, iOS11, Conductor/W20/Tidal
3. only Aurender can explain/fix the specific issues
4. these issues do not detract from the great SQ of Aurender products
5. we need to read all of the above correctly.
