background play not working with streams only on one phone

so I've got a Google pixel 6, and a Google pixel 8. I exported the settings from revanced on the 6 and sent them to the 8. I've double checked that background play is turned on for everything, but background play doesn't work for live streams on my Google pixel 8. background play still works for normal videos, and the background play works for live streams on my Google pixel 6.

is there a setting I'm missing?
