One of my Pro devices has just received this firmware, but my other Pro is still waiting.

After my Pro received the update it disappeared from WiiM Home App. I had to cycle power to get it back, and then I had to go through setting it up again like a new device. Is this normal?

No, it's not.

Looks like the Pro was factory reset.

Thanks. Sounds like this has just exited beta. Interested in people's experiences with it.

It has been in main firmware for the Ultra for some weeks now.

It works very well and allow me to RoomFit my setup to a neutral sound and then apply the EQ on top of that depending on what I am listening to.

I like to have a little more bas when playing at low volume and the RoomFit gives me a very controlled and tight bas in that case. At high volume I just turns the EQ off and the RoomFit profile still keep the bas in control.
