How to recover deleted Messages that were synced to Messages in iCloud?
I've updated my devices, both iOS and macOS. I've enabled Messages in iCloud on all devices, and allowed them all to sync to the cloud. If I log into iCloud, it now shows 22gb of space being utilized by Messages. So everything appears to be configured correctly and syncing properly across all devices.
So if I delete a Messages thread between myself and another person, how do I now recover it? My assumption was that I could delete message threads from my iPhone, and I'd be given the option to load the history of that conversation when a new message from that person comes in.
I tested this by messaging someone, and then deleting the conversation. When their reply came back, I see no way of recovering the message history between us. So I'm either missing something, or perhaps I've misunderstood the purpose of Messages in iCloud.
