When uploading content to Adobe DPS, you may run into a situation where this content does not appear in the Adobe Content Viewer.
This can happen when the state of the issue is set to 'private/paid (a combination which is normally not used).
Such a combination can occur when the issue was marked as 'paid' by setting a common metadata field and published for the first time (during which the issue is automatically set to 'private').
To resolve this, set the paid flag in Content Station for the issue to 'free' while leaving the status of the issue set to 'private' and subsequently update the published issue.
Note: When you want to make the issue public you will need to remember if the issue was set to paid or not and set this accordingly.
