Deleting iMessages from iCloud
I've reviewed a lot of articles relating to purging Messages from iCloud backup, but they seem to be referencing previous versions. I've got an iPhone 12 mini running iOS 16.3.1 and Messages 14.0. Diving into Settings it's showing me I have (after deleting a lot of my threads entirely, from what I can see from my end) only ~410MB of data being used for Messages, but iCloud is claiming I am using 4.55GB for them. I've disabled the Sync option to stop adding additional Message history to my "full" iCloud account, but I cannot account for the discrepancy. I used the option to Disable & Delete, but it's telling me that I have to wait 31 days until the messages are deleted from iCloud? Is there a way to expedite their deletion?
