Removing features in "updates"? – Dropbox: Cloud & Photo Storage Review

My use case is mostly managing music and pdfs on an iOS device, since as a Linux user apple makes that baseline literally impossible. Dropbox sort of helps with that miserable situation. But AFAICT Dropbox removed the "make available offline" feature in an update. Removing features in updates? That's terrible anti-user behavior. Other problems: doesn't seem to do incremental downloads, so is hopeless on slow or flaky networks. Interrupts downloads when you close the app. Dropbox and apple, surely you can do better.
