I had 2 in stereo but it kept playing out of sync. So I keep them all separate now. I constantly get error messages saying there not connected to the internet. It’s never all 3 at once but 1 of 3 will randomly drop internet. When telling them to play every where it’s rare all 3 will play. Or 1 will play 1 song and the others will be playing another song. Anyone else with multiple HomePods having issues? Or any idea what will cause these problems.
