Listening progress wasn't updating when the app was playing in the background

### Expected behavior

The listening progress updates even when the app is playing in the background.

### Actual behavior

> Here is a log file right after listening to a podcast fully in the background and having it not advance to the next podcast. In addition I just came back into the app right now to see what was happening and it’s showing that it’s only 17 seconds into the podcast that I just finished listening to and “playing” but it’s hung.
