Adding Layouts to the Device Playlist
Each of your devices/screens has a playlist which has 1 or more of your layouts.
To add a layout to your screen's playlist, go to the Screens page. Here you see a list of all of your screens. To the right of each screen is an edit buttton.
Click the edit button, then you can add, delete, and sort the layouts on your playlist. Note, with the light and standard plans, you can only have 1 layout per screen.
When you have just 1 layout on a playlist, it will loop continuously. If you have more than one, it will play all content in the primary zone, then move to the next layout and start over when all layouts have played.
