Brand new HomePod Mini stuck on "being configured"

Sorry to hear about your experience. I have 2 HomePods connected to the Apple TV in the Living Room and 2 HomePods as a stereo pair in another room. They all are used daily and never had a problem with them.

They are listed on the Support Page, but it is under TV. I suppose because they are frequently paired with the Apple TV, but I agree, they should either have a label called Home Entertainment or list each device separately.

I've been having a problem with my HP Minis. One connects, the other doesn't. I searched everywhere, tried ALL the things multiple times, nothing worked. There was one piece of advice in there that I ignored though b/c I *knew* that wasn't the issue.

CHECK THAT YOUR DEVICES ARE ALL ON THE SAME WIFI NETWORK!

Sorry for shouting, but I *just* realized that at some point, and not by my hand (purposefully), my laptop was connected to our Guest wifi. Once I switched it back (after DAYS of trying to figure this out and even window shopping for new, non-Apple speakers), it all worked fine. I'm not saying that's your issue, but heck, it might be. :-) Good luck!

I own a HomePod and a HomePod mini and experienced this issue with my Mini version. I used my Mac to perform a restore an it and also to update it to the latest firmware version. I have had zero issues since I did those two things. Sorry to hear it didn't work out for you.
