I still just wish their email sign up system actually fucking worked. Never got a chance to try fountain.FM. Even after 16+hours of trying.
I just subscribed to nostr:npub1v5ufyh4lkeslgxxcclg8f0hzazhaw7rsrhvfquxzm2fk64c72hps45n0v5 Premium.
The best feature I’d get: Supporting development!
Fountain has come a long way since I tried it first and I want to see it beating any other podcast app out there! 💜🧡

Have you tried using your phone? I remember long ago I was only able to login using phone.
Everything. Multiple phones. Multiple email addresses. I could get the sign up code, but then their own system says it is the wrong code. Tried contacting fountain.FM support and got an auto generated email saying they are understaffed so I probably will never get a response.
That really needs a fix.
