Thanks for coming to the Spotify Idea Exchange and voting to make this happen.
We're happy to announce that we've implemented New Episode Notificationsand they're now available on iOS and Android mobile devices only.
How will New Episode Notifications work? Starting August 17th, a Push Notification will be sent when a Show that users subscribed to releases a New Episode. Users won’t receive notifications for Episodes that they have already listened to.
How do I subscribe to New Episode Notifications? From mobile, users can subscribe to receive notifications using the Bell icon on the Podcast Show page. If a user hits the Bell, they will automatically Follow the Show too. Users can also subscribe/unsubscribe by navigating to Notification Settings in the Spotify app, and selecting notification Settings, which displays all their followed Shows and subscription status.
Once again, thanks for helping us make Spotify better, by participating here on the Community.
