I only used that once, but it fixed all the months of odd syncing I had experienced.
Had the same problem and this fixed it.
Perhaps it’s a Heisenberg type situation where measuring whether a file is synced itself changes the sync status.
Deleted messages would disappear in Big Sur. But read status wasn't synced for unread messages
In Catalina if you delete an unread message on iOS, it will disappear on MacOS, but Messages will still have an "1 message unread" badge.
You might also be told that you are supposed to delete those messages on every device and that if you expect it to work automatically then you don’t get it.
