I am beyond ecstatic to find that the latest iOS 10 beta has an "Add to iCloud Drive" button in most share sheets that I can see including third party apps. I would say that this finally puts iCloud Drive basically on par with Google Drive, Dropbox etc. I have been baffled for years that Apple never had an easy way to add files from one app into iCloud Drive. I have submitted multiple feedback requests for this change. Is anyone else pleased to finally see this addition?
