I have created testfolios to test out the different functions.
I deletet them from the folio producer and InDesign but they are still able to download in the content viewer.
How can I delete them completely?
After you delete a folio in the Folio Builder panel or in the Folio Producer, the viewer should no longer be available for download on your device. If you already downloaded it, tapping Archive should remove the folio entirely.
There isn't enough screen area on the iPhone for an Archive button, so you need to delete a folio on the iPhone the same way you delete podcasts and mail messages--by swiping from right to left to display the red button.
