Would love this, but... – Podcast App & Player - Castbox Review

I am totally stumped on why an app like this would require wifi/cellular access to play already downloaded episodes??? Huge issue for me. I fly often and will be going back to Casts which allows downloaded podcasts to play, well, like downloaded content. Like most of what goes on with this app, but this is a deal breaker for me.
