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.
Try AntennaPod, it’s on F-Droid
I’m kind of into Podscast Addict. Not sure how it compares, but its pretty good.
It’s not open source
One of the best apps on any platform
