Premium Podcasts Not Always Showing In Feed

I have premium shows that don't show up in my podcast app sometimes and there doesn't seem to be any rhyme or reason to it. Some episodes of Grubbsnax weren't showing, now the last like 3 episodes of Albummer aren't showing up in my app. Not sure if there's some issue with how they're going out or if it's on my end.

They all have their own feeds.

@permanentsigh: well that would explain it. I'm sure they mentioned that and I missed it. Thanks!

They do, but that doesn't explain why they sometimes show up in the Premium feed and sometimes they don't. Are they not going to populate into the larger Premium feed at all anymore? I would prefer being able to see everything in the one feed, rather than having to subscribe to each individual feed.
