Ok, I reviewed Pocket Cast’s FAQs again and they say they now require the member-ID /password format for protected casts. That is: https://[member-ID]:[password]@thebritishhistorypodcast.com/feed/members. Unfortunately, I’ve entered this twice (deleting the cast,restarting the device, rechecking my ID and password) and Pocket Cast can’t find the app, this way. I can only find it By entering the email address without an ID or password and the getting Members’ episodes from months ago. Puzzling.
