At least one customer could not find articles in DrEdition content source for print product from 2021-05-28 08:24 to 09:26 (Duration: 62 minutes). The cause was deployment of a timezone feature that had unintended consequences for content source based inboxes in DrEdition for print. First and only report came in at 09:09 (#ZD-14220), and the fix was to roll back to previous version which was done 09:26, 17 minutes after first reported error.
