How do I add content to my playlist?

Tap on the three stacked dots next to any session that appears in a list, and then tap “Save to Playlist.” A new screen will open and you can add a checkbox next to any playlist you want to add the session to. 

Alternatively, you can open the player and tap the bookmark icon. The session will be saved to the My Saved Sessions playlist by default, but you can tap the bookmark icon again to change which playlists the session is saved to.
