Rule of Google: if it works, kill it.
I know, I know, using Google apps isn’t the best, but this was a perfectly good Podcast app with all the features you might want.
Apparently they’re moving everything over to YouTube Music, where a lot of the features of Google Podcasts aren’t implemented yet.
I’ve moved over to an app from F-Droid.
It does podcasts perfectly. Select podcasts as your library and then add in the podcast URLs
Nice! I shall give that a try later on
