One daily news podcast stopped updating in Apple podcasts on iOS 18.0.1

After the update to iOS 17.7, one daily news podcast stopped updating. I've updated to iOS 18.0.1 but the issue continues. I have unfollowed and re-followed the podcast repeatedly, after which I can download the latest episode for that day, but the next day the newest update does not appear in the program feed and the podcast does not move up in the latest episodes screen which is set to order by date updated. I have also removed and reinstalled the Apple podcast app several times. This fixes all issues but on the following day, they return as before. I also erased my iOS, reinstalled it from iCloud, and deleted all settings with the help of an Apple advisor but this didn't solve anything and it took me a week to restore my iPhone. I started using both Spotify and Pocket Casts and both update this podcast without a problem. Is this an issue with the Apple podcasts app or iOS 17.7-18.0.1? Why only one particular podcast? Very strange indeed. Any helpful suggestions, advice, or support would be most appreciated. Thank you.
