Where can I find my downloaded episodes in my SD card/internal memory (Android)?
Could you please have a check if you could find your downloaded episodes by going to the phone My Files - SD card – Android - data - fm.castbox.audiobook.radio.podcast - files?
If you stored downloaded episodes in the internal memory, to find them, please go to your phone My Files – Internal storage - Android - data - fm.castbox.audiobook.radio.podcast – files.
For Pixel phones, to find your downloaded episodes in Pixel, you could go to your phone Files (Show internal storage) - Three vertical lines on the top left corner - Pixel XL - CastBox - Channels. The downloaded episodes are arranged by Channels.
