IOS Podcast App. Its absolutely terrible. Stops playing in the middle of episodes, forgets what episode it is playing, episodes disappear, and it throws up a spinning wheel again and again...
I moved to Spotify in order to get my feeds synced across devices. It’s mostly been a better experience, but for some insane reason you can’t add a proper feed to Spotify.
I don't have issues with the app not playing or forgetting episodes, but I do absolutely loathe how it hides played episodes automatically and makes me go find them if I want to listen again.
