Original Post We’ve discovered that Apple's new iOS 8 introduces a compatibility issue that may prevent Dropbox and Carousel from properly uploading your photos and videos. This means that only the contents of your “Recently Added” album will upload automatically. If you upgrade to iOS 8, don’t delete photos or videos from your devices until you’re sure that your stuff has backed up to Dropbox. Please visit our Help Center for additional details on how to keep your stuff safe. To avoid any confusion over what’s been backed up, we’ve pushed a Dropbox and Carousel update that temporarily suspends automatic backup of photos and videos.

Thanks for your patience, and sorry for the inconvenience.
