This is an issue specific to a third-party app. Dropbox is failing to provide the item.

To report an issue with a third-party app, please contact the developer of the app directly by using the support link located on the app's page within the App Store.

Please contact Dropbox developers.  There is no Apple issue here.

Please close your feedback report, or let us know if this is still an issue for you.


This appears to be fixed.
