Song in Music on MacBook Air won’t show in library on iPhone

Pretty vexed here. I recently upgraded to Big Sur iOS and now my cloud music library in Music won’t sync and each time I try I get a message reading “Genius results can’t be updated right now. The network connection was lost.” I’ve tried rebooting, signing out and back into my account on both my iPhone XR and MacBook Air, all iOS are up to date on both as well. I’ve got one song I’m trying to add to a playlist in music on my phone and nothing is working. Please help!
