You can set your kiosk settings to priority download if you want to make sure that all content in that kiosk is automatically being downloaded by the app.
We had this feature before on publication level, but now it's also possible to set a whole kiosk automatically. This can be very useful when all content in a kiosk need to be up to date.
Select the kiosk > Settings > Default edition priority > pushed any connection
Wait until the Kiosk is successfully saved.
Once you've done this, all newly added and synced content (PDF, video and interactive publications) will be automatically downloaded and up to date.
