Messages deleted on one device are not deleted on other devices
I have a Macbook Pro (15" 2018), iPhone 12 Pro, iPad Air 4th gen, and Watch 5th gen. When I receive spam texts in iMessage and delete them on one device, they remain on the other devices until I manually delete them there too. Every other action seems to sync across all of my devices. All devices have been restarted several times with no change to the issue. I have signed out and back into iCloud on all devices once or twice with no change. This issue has consistently happened for the past year and I finally thought to post about it.
Has anyone else observed this issue? It would only be a mild annoyance if the spam messages weren't frequent and sometime sexually explicit. I should expect if iCloud syncs all of the other actions (notes, music, contacts, browser favorites, photos, messages sent and received, etc.) that it should also sync messages that are deleted.
