Homepod Stereo Issue

Hello all, prior to today I had no issue with stereo pairing with two Homepods. This afternoon they both starting acting on their own. I have removed and reset each unit individually. I have restarted my home app. I can get stereo sound to play when I stream apple music from my iPhone. When I try to get the units to play without air streaming they play separate music and respond as if they aren't connected. Units are updated to 11.4 Driving me insane, any thoughts?
