Songs on iPhone won't play on Homepods

My wife is a Family member on my Apple music account. She can play all tracks on her iPhone but certain tracks just won't play on our Homepods & HomePod minis; instead, another track plays! Both HomePods and her iPhone are on the latest software iOS 18.5. I can play all songs from my iPhone on the Homepods without issues. I've tried logging her out of iCloud, closing and opening the Music app, shutting down and re-opening the phone, closing and re-opening Bluetooth and wifi all to no avail. The issue has to be with the phone (12 mini) as I don't have any issues with my 12. Any advice would be most appreciated.
