AirPlay not working on one of two Pro Plus (Spotify Connect works)

[Burnside]

I’ve contacted Wii support and will be having the device replaced. Support suspects that there really is a fault with it. It will take a little while longer for the whole process to be completed.

Good news and it underlines the importance of raising a ticket in the WiiM app - the device logs often have information that's not evident otherwise.

Hello everyone,
The device in question was indeed faulty and has been replaced. It wasn’t an Essential version either. The new Pro+ is working perfectly – so the setup was correct after all. Thanks for all the helpful tips!
Best regards
