Most likely fountains premium changes and the preview bug. You can try pressing it a couple times and it may play.
Avi and I did premium for Plebchain Radio.
For us, we don’t have ads but there is a one day delay for not subscribers and we also release extra episodes and content for subscribers.
BUT - it’s brand new so the fountain team is squashing bugs. I’ll forward / report this to the direct channel I have. 🫡
