Was it a Bose? I once bought Bose headphones and downloaded an app to pair it. When Bose recognized the headphones, it told me that I had used the wrong app to pair to those headphones.
@snow_bunny Nah, it was Sonos. Which, I guess the app ecosystem is their whole thing - but I didn’t know that at the time. I just wanted a basic sound bar, and the reviews didn’t really mention that all that extra fluff was mandatory.
In retrospect Sonos sucks for a lot of other reasons too, so I guess it was a bullet dodged.
