After you purchase a subscription on a device, the subscription tile disappears. However, the most recent folio still shows a purchase price and the button next to it is labeled "Buy." The expected result is that the most recent folio's status changes to "Purchased" and the button next to it is labeled "Download."
If your most recent retail folio has renditions published, ensure that all of the metadata, especially the publication date, are identical for both renditions. The publication date, in particular, requires careful steps to ensure the invisible hour, minute, and second timestamp associated with the folios are the same.
If a folio is published without the user visiting the Publication Date widget, the Publication Date value on the fulfillment server includes the exact time the publication process was completed.
Note: The time zone of the computer where the publish command is made influences the time value when using the computer's Publication Date widget. Therefore, make sure that the publishing renditions are done from the same time zone.
Adobe hopes to eliminate the need for these additional steps with the Publication Date values in a future release of the Digital Publishing Suite.
