Just thought I would point out there is a nice podcast downloader for docker that will let you easily add podcasts to Jellyfin. I added them as a music library. It isn't perfect but it works pretty well. It will search for podcasts you want and auto add them to be downloaded on a regular basis and it will also download the old episodes if you want as well.

Will check this out, but always interested to know how others handle this
