If you subscribed, via WordPress, to just *some* categories of posts, you might not have been receiving anything for some months…. because the new Gutenberg editor did not show Categories to me. Silly me, I did not realize how a big a deal this was until today. So, today, I restored the old editor. Now I see the categories into which I categorize. So, now, you should be receiving those categories to which you have subscribed. Hope this works better.
BTW, I get a lot of spam comments — all wanting to sell random things. If you listen to the podcast,then you know my email. And you also know this is a podcast ministry site. LOL. Nevertheless, always looking for interaction with my listeners.
