I really just saw this Join App Betas: Android (mobile), Android TV, Apple TV, iOS and signed up when I first got my SHIELD.
Like me, you’ve been around long enough to know that when you really need help here, you’ll get it. Be that from other users or from the usual ninjas, team members, or employees. Folks like Chuck, Otto, BigWheel, Zoidberg are very quick to respond, so no complaints from me there 
For this particular issue, I agree with you that the lack of feedback is a little concerning, though. The SHIELD, being the very best overall playback device, deserves some extra TLC
