For a handful of listeners, The Sideshow feed (mainly in the Apple Podcast App) stopped updating. It most likely had to do with a recent hosting/server change, but there appears to be an easy fix.
Add this podcast feed into Apple Podcasts

(If you don't remember how to add it, just tap on "library" at the bottom of the app. Then tap the three ... dots at the top right and choose "follow show by url" and paste or type the new feed in)
After the new feed is added, you should see the new episodes that you've been missing. In addition, the original Sideshow feed will also start working again. I have no idea why. Technology is weird
