I recently went through my Messages on my iPhone and deleted most photos/videos after backing them up separately. I got my Messages storage down to about 300 MB of space on my phone. However, in my iCloud storage, the Messages still take up 1.5 GB. Looking at the messages from which I deleted them, the photos/videos show up as a button that says "Tap to Download". So it seems that even though I've deleted them from the messages, they're still stored in iCloud with the Message. How can I fully delete the attachments from iCloud?
To be clear, I don't want to turn off storing Messages in iCloud; I still want my Messages there, I just don't want these photos/videos that I've deleted to be there anymore. Is there a way to actually delete them from iCloud? I have tried turning Message syncing off and then back on again, but as soon as I turn it back on, the 1.5 GB shows back up.
I feel like I've scoured the internet with no clear answer on this.
