Album art on iPhone doesn't match album art on MacBook

In the Apple Music library on my iPhone 16 Pro, the album art doesn't match the correct album art in the Apple Music Library on my MacBook. This problem began when I moved to the iPhone 16. I have verified that all of the album art on the MacBook is correct. On my iPhone , for several albums artwork for other albums by other artists is shown. For example, the album artwork for Adele "21" is shown for Bonnie Raitt "Road Tested". The Adele "21" artwork is the one that is misapplied to other albums. I have tried deleting the artwork from the Adele album on my MacBook and re-syncing my phone with my MacBook but that didn't change anything. I have turned off iCloud on my iPhone and turned it back on again - no help. I have deleted the Adele album entirely and re-synced my phone. None of these attempts have corrected the problem. In addition to the album art problem, several albums also now appear several times. The aforementioned Bonnie Raitt album appears TEN TIMES in my iPhone album library. Help!
