I have had issues with the app. It downloads episodes and was keeping them indefinitely. Not ideal, but there were some settings I had to adjust. The default never deleted anything and it was filling my phones disk up. The default should be less of a disk hog. Will need to pay attention to the setting of downloading over WiFi only. 
I keep finding nostr:nprofile1qqsx2wyjt6lmvc05rrvv05r5hm3w3t7h0pcpmkyswrpd4ymd2u09tscpz3mhxue69uhhyetvv9ujuerpd46hxtnfduq3kamnwvaz7tmwdaehgu339e682mnwv4k8xct5wvhxxmmdqywhwumn8ghj7mn0wd68yttsw43zuam9d3kx7unyv4ezumn9wscn3xgh to be quite a data hog despite having the Downloads preset for Wifi only.
Is that a common issue?

I had the same issue. That was easy to fix, but I agree that changing the default would make sense.
The data download, I don't remember what's the default there. But despite having it on Wifi, I somehow keep draining the data there much faster than expected.
