Got the latest public beta with Messages iCloud sync. Syncing of messages works well for the most part, but not completely.
On everything I have, all the messages show up just fine and delete and so forth and maintain sync. But not all photos sent via messages show up on all devices. In specific, one message doesn't show the photos on my iPad (non-pro), but does on my iPhone 7+, my Macs and my iPad Pro (original 12").
