Comment 2 for bug 912627

Digging into this it does indeed appear to be tied to location services. If I delete the app, reinstall and answer no to allowing location services uploading of images from the camera roll does not happen.

Likewise if I try and add an image from the library it won't upload after I've answer no to the dialog requesting access for location services.

Clearly the "silent" failure needs to be fixed and a way to reprompt for location services access is necessary to the user experience.
