Yes. The entire platform -- hardware & software -- is just a mess. I bought an MDC phono module for my digital amp only to discover it wasn't supported by its firmware. I waited 18 months to be able to actually use it. I experienced the same non-persistent configuration problem you described and also very sketchy things like the power button simply not working. Unacceptable by any measure and at any price point as far as I'm concerned.
