I have a very slow internet connection (not by choice). Last night from the Photos, I chose to download a video (12 min) from the iPhone 7 to iCloud drive. It has been working all night and morning, clearly is going to take forever, is slowing down everything else, and I just want to cancel the download to iCloud drive. I have searched and researched, and I cannot find where/how to do this. Just need to cancel a download to iCloud drive that is in process. Any help?
