Device labels are used to filter devices on Devices section. For example you can create a label such as “43 inch”, and add this label to all the relevant devices. When you are on Devices section, and would like to list these devices, you can enter “43 inch” into the Label field.
Moreover, while creating a playlist, you can prefer to or not to display an item on certain devices. You can do this by selecting the label of the device in the display rules section of the item. For more information on display rules, visit Display Rules.
How do I add device labels?
Go to Devices section.
Click on the device you would like to add label on.
On the Labels row, you can enter new labels or select from the previous labels you created. You can add as many labels as you want to.
After you finish, click on the Save button at the bottom of the page. You should see a green notification at the top-right of the page, indicating process is a success.
