Same here

Check the language settings, make sure the top one is selected, undefined I think.

I kept stumbling on communities with no posts or a couple yet the sidebar showed lots, it was my language settings.

You inspired me to look at antennapod and within 10 minutes pocket casts was uninstalled.

Been using pocket casts since the beginning but starting to get fed up with apps wanting more and more of my money.

I noticed lots of posts were missing, like some communities were completely empty but in the sidebar it showed as having dozens of posts. I went to settings and made sure I had English and undetermined selected and suddenly they all appeared.

Not sure if that would be the same for comments but worth trying.
