Messages storage on iCloud
3.5GB of my iCloud is taken up by Messages, according to iCloud - Manage Storage on my iPhone. But when I click on Messages, it says Conversations only take up 450KB. How is this possible? I've deleted most of the messages on all my devices (iPhone and MacBook) but I can't seem to figure out what / where this last 3.5GB is coming from so I can delete it. Any advice please?
