Has anyone ever been able to get help from NAD

Did you contact one of the factory authorized service centers?

@sfseay Had a similar experience with my M10.

I’m about to do the same with my M50.2.   Love the sound and the form factor that realizes that DAC-tastes vary and assumes the owner has his or her own DAC.   The BluOS software can be quirky and the documentation for it almost non-existent.  NAD’s customer support was atrocious and the value of it approached uselessness.  

Unless you are upgrading from a prior BluOS platform and will never need assistance in terms of written instructions or, God forbid, help from NAD, don’t buy an NAD BluOS product. 

Completely off subject, but fifty or so years ago, my Kenwood Receiver (tubed!), stopped working. I went to the tiny storefront that served as Kenwood’s repair station in L.A., and a guy who only spoke Japanese gave me a new one.
