Need to re-download podcasts

I’m having issues playing podcast episodes that have been previously downloaded. The app will not play them and though there is a play button next to the episode, it will not play.

Clicking the play button then reveals a download icon. Really annoying. This used to be very infrequent but now it is becoming more and more frequent.

Anyone else have this issue or know how to avoid it?

This happened to me then being in a not stable/reliable WiFi-Network.
