“Playlist” consists only of episodes you’ve added (by clicking the “three lines and a plus” button). “Next Up” shows upcoming episodes of a podcast you’re currently listening to.

Instead of the “Playlist” order, Castbox will default to and prioritize the “Next up” order. This might cause that some episodes in your playlist to play out of order.

For example, if you play an episode directly from a channel’s page, your “Playlist” order will stay the same but your “Next up” list will show a list of episodes from the channel that’s currently playing.

Or, if you choose to play an episode directly from your “Downloads” list, your “Next up” list will consist of episodes in your “Downloads”. Even if this episode is also on your “Playlist”, the “Next up” list will still follow your “Downloads” list because the current episode was played from the “Downloads” list.

After you finish rearranging your “Playlist”, please pause the episode that’s currently playing and resume by tapping it in your “Playlist”. This way, the episodes in your “Next up” list will be updated to the same as those in the Playlist that you have just arranged.

If you’re currently using the purple version of the App on Android, you’ll need to update the app to the orange icon version.

To activate Castbox on your Echo, go to the Amazon Alexa app and search for Castbox under Skills. Once added, link your Castbox account to your Echo, and you will be able to play episodes from your subscribed shows as well as many others.

After you’ve set up the custom skill,  if you want to listen to This American Life using your Amazon Echo, all you need to do is say “Alexa, ask Castbox to play This American Life,” and Castbox will either resume your last played episode if you have subscribed to the channel, or it will play the newest episode if you have not. If you were listening to This American Life from a previous session, you can also just say “Alexa Open Castbox,” and it will automatically resume from your last played position.

You can also skip past a section of a show by fast forwarding through the parts you don’t wish to hear. To do this, simply say “Alexa, ask Castbox to fast forward xxx seconds/minutes.” You can also skip directly to the next episode of a channel as well by saying “Alexa, next.”
