Really difficult to use offline – Podcast Source Review

I recently downloaded some episodes to listen to offline while I travel, but whenever I try to returning to the window while an episode is playing, I get like 20+ "no network found" error messages in a row, preventing me from rewinding or pausing or whatever, and it's getting really annoying. It happens whether I'm on airplane mode or just not connected to a network. Why is there no adaptation for offline listening? Doesn't that just defeat the entire purpose of downloading an episode?
