When I leave my WiiM Amp in standby, there are often (about twice and hour) beeps and bong sounds emanating from the speakers, and the status LED goes bright again showing active mode. I can’t be certain, but I don’t think this happened before yesterday’s updating of the firmware and WiiM Home Apps. I’m using WiFi internet connection and the settings say that the 5Gz field strength is ‘Very Good’. Sorry if this is a known bug…..
