Stereo HomePod Mini not working properly with Apple TV 4K.
I recently bought an Apple TV 4K and have been trying to get them to work with my two HomePod Mini's to no avail. Right now, despite saying they're in stereo pair I can only hear sound out of one of them. On top of that, the sound itself jitters, the best way to describe it is as though all sounds drops for just a split second repeatedly, only for it to work regularly, then repeating.
They're all connected to the same wifi (school wifi at that), and I've tried restarting, resetting, removing iCloud from ATV, etc.
I've no idea what to do.
Apple TV 4K, tvOS 15
