how do i manage playlists on my galaxy watch 4

[ThirdNebula]

I use spotify on my galaxy watch 4 and phone. the watch app usually lets me add and remove a song from my playlists, but its not working. I am able to edit playlists like normal by opening my phone, but the watch app just shows the + button, and clicking it does nothing (except trigger haptic feedback). If i play spotify from my laptop, the + button works fine, displays a check mark where applicable, and lets me select the playlists i want to add/remove from. This feature was working on 9/30, but as of yesterday i noticed it was unresponsive.

i have restarted my phone and watch. force stopped, cleared the cache on the app on my phone, and reinstalled on my watch. i have the latest software, and all other watch functions seem normal, indicating a good connection. i have logged out and back in on my watch and phone. i even completely reset my watch. if there's any other general troubleshooting steps i missed, please let me know. what is really puzzling me is that when i play on my laptop i can use my watch perfectly. If i switch devices to my phone, it stops working again.
