3. Check to see whether “Custom” is chosen in the “Add Episodes From” box. If that’s the case, your watch might be loaded with podcast episodes. There are no podcasts on your watch if you see “Up Next” selected.
The “Choose Shows” feature displays a list of all the podcasts to which you have subscribed in the iPhone’s Podcasts app. All podcasts that are enabled are set to keep the three most recent episodes on your Watch.
4. Tap “Up Next” in the “Add Episodes From” box to remove all podcasts at once. This will remove all podcasts from your watch list and only show you the current episode.
To remove all episodes of a single podcast, keep the option set to “Custom,” but switch off the chosen podcast by swiping its button to the left. This will delete all episodes from a specific podcast but keeps the episodes from the other podcasts on your Watch.
