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.
They have an agenda, which isn’t aligned with your agenda. They only care about profitability, so they kill any projects not supporting that goal. Some projects are created to gather specific data sets about users, and the project is shut down when the data is captured, regardless of how popular the project was. They are always doing something with an ulterior motive. Once you understand that then you won’t be mystified by their decisions anymore.
