For end users
Can I also download the InDesign package from a created design?Yes, this is possible. Just the admins can download these files to make minor adjustments or share the output with an internal designer or agency.
This is a setting that can be adjusted in the admin. Go to 'Pages' → 'My Documents' → Module: 'Outliner' and check the checkbox in the right sidebar saying 'INDD Package for admins'.
