I've followed all the instructions and guides to reset my HomePod. I've plugged and unplugged dozens of times and held my finger on the top for over a minute. But nada. Siri still seems to work for simple questions but the Pod doesn't show up in the Home app and it won't access my Apple Music account. If I just touch the top it will start playing some random selection of music. It used to work fine, I had it paired for stereo and loved it. I started having problems with one or the other Pod dropping out and I've had to fiddle with wifi multiple times. I'm wondering if it got messed up somehow by the iOS 12.1 beta?
