Hi @ahnjh113, thank you for reaching us to the Sonos community, and appreciate you for bringing this concern to us. Let me help you with this.
We apologize for the inconvenience. This issue has been reported to Apple but we don't have any further information to share. It may look like that this is a Sonos issue but the cause is at Apple's end (Apple pushes what is displayed on Sonos). We recommend contacting Apple support to further assist you with this.
You can try to search for a particular album within Apple Music > My Music on Sonos app. You should be able to see the album in your library and play it.
Please feel free to reach out in the future if you have any other questions.
