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.
You should switch to AntennaPod.
That’s my go to, FOSS app that rivals the major apps.
There are other podcast apps on F-Droid also.
Antennapod is fine, although it is annoying that there appears to be no way to make it so that it automatically plays the next episode of the podcast you are listening to rather than what you purposefully place into the que.
