I installed Amazon Cloud Drive a couple of months ago on my iPhone 5, and all my photos uploaded successfully. Went to check the app a couple of days ago, and not a single photo has uploaded since. Deleted app, reinstalled, and tried re-uploading. App shows pictures uploading successfully, but nothing appears in the albums on iPhone app and folders are also empty when I sign in to Amazon Cloud Drive online. Am I missing something? Any suggestions? Thanks.
