Turn on "Network standby" (Onkyo/Pioneer: Setup → Hardware → Network; Yamaha: Setup → Network) on the receiver. Without it, the receiver switches its network off in standby and cannot be woken.
Ampline shows the volume in the receiver's own unit (dB on Yamaha). The slider sends one value when you let go. Set your volume limit in Settings: above it, Ampline asks once before sending the higher value.
Ampline shows a change as done only when the receiver reports it. "Not confirmed" means the receiver did not report it in time; the receiver's real state is always shown.
No. Ampline talks to your receiver only on your home network and has no cloud service.
