Aurender is extremely glitchy, period. There's an Aurender Facebook group and 50% or more of the posts are complaints. I hope they figure out their software, because if they don't, it will sink the company.
I recently had an issue with my streamer that prevented it from working at all. I could not play any music through it (Qobuz, internal drive, and internet radio did not work). I uninstalled and reinstalled the app, updated the streamer's software, cleared cache, rebooted the router, rebooted the streamer, you name it. Two hours of my life were gone. Nothing worked. Finally, out of pure desperation, I did a factory restore of the streamer which brought it back to life. It's frustrating, for sure.
There was also an issue with Vtuner in mid-December that supposedly effected everyone. That's now sorted out, so I finally have full functionality. I'm dreading the next time the app, the streamer, or Vtuner freaks out, because I know that it WILL happen again.
