I have iMessage Sync on and the data it's currently using up is in the tens of gigabytes, however after I updated to iOS 18, all of the images I used to have in my conversations are essentially gone. There's only about 5-10 images in each conversation. I have tried toggling the "sync" on/off in iCloud, it then spent the day basically syncing but to no avail. I think it added like 3-4 photos but that's about it. And no, the toggle for "download images" or whatever it is exactly in the conversation contact information page isn't there. All I have " turn on contact key verification" but nothing else. Does anyone have any ideas?
