Stereo Homepod 2 drops

I’ve got a pair of HomePods 2 that I’ve stereo paired. I’ve noticed songs (especially Dolby atmos songs) seem to somehow fall out of sync. The songs will keep in step, and play the same song at the same time, but they lose the stereo pairing and it gives it kind of an echoing affect. I’ve noticed if I restart a song or change a song it’ll work ok, but if I select an album or playlist they eventually will start having this problem. HomePods are set to automatically upgrade. I’ve restarted, unplugged, etc. I’ve got WiFi 6 mesh network and pay for a high speed. Regularly clock over 600mps on my iPhone and a gig+ on wired connections. I’m not sure what else it could be except for WiFi interference? Anyone else have this issue?
