Please ensure that your playlists are set to Public and that you are following them in your Spotify account. To set your playlists to Public, go to the Spotify app, select the playlist, tap the three dots in the upper left side of the screen, and tap "Make Public".
Note: Daily Mixes are dynamic playlists that change daily and do not have a set number of tracks won't be available in the Mighty app. They cannot be taken offline like a standard playlist so they are not included in the Made For You section of the Mighty app. As a workaround, you can save a Daily Mix as a standard playlist via the Spotify app. Go the the Daily Mix, click the three dots next to the "Play" button, and select "Add To Playlist".
If you still can't find your playlists in the Mighty app please email us at email@example.com and we'll respond within one business day to help you troubleshoot.
