There could be several reasons why your Apple Podcasts is not updating with new episodes. Here are some potential solutions:

1. Check Internet Connection: Ensure that you have a stable internet connection. If you're using mobile data, make sure that you have enabled Apple Podcasts to use it.

2. Refresh Podcasts: Go to the "Listen Now" section and pull down the page to refresh it. This action prompts the app to check for new episodes.

3. Update the App: If you haven't updated your Apple Podcasts app in a while, it might be a good idea to do so. The latest version may contain bug fixes that solve your problem.

4. Check Podcast Settings: Some podcasts allow you to customize how new episodes are downloaded or updated. Check these settings to ensure they're set up correctly.

5. Re-subscribe: If none of the above works, try unsubscribing from the podcast and then re-subscribing. This action can force the app to update with the latest episodes.

6. Restart Your Device: Sometimes, the simplest solution is to restart your device. This action can clear out temporary files and processes that might be causing the issue.

If none of these solutions work, you may want to contact Apple Support for further assistance.
