I've had an Ultra since last summer and really enjoy it. The past two months or so I've noticed I'll walk into the room when the unit is in standby (not playing and clock should be displaying) and see that it has switched itself to Bluetooth input. I've only ever used the Wifi input and have never paired the Ultra with any Bluetooth device, either input or output. This happen every few days and I've spotted nothing that would explain it. It never happens while its playing music. When it does occur, I can quickly set it back to Wifi input with the phone app so its not been a big issue, just a curiosity. I've never noticed this issue with either the Pro or Pro Plus I have in other systems.
Any thoughts?
