I got an email back from them. Hi Hayley,
Thanks for contacting Episode Support!
The current series of VIP automatic-recurring subscriptions have been discontinued in the Episode app. This is the reason why they are currently unavailable for purchase. New special offers should be available within the next few weeks. We apologize for any confusion this may cause.
Thanks for playing!
This might mean that something new is coming soon hopefully it’s back to being unlimited no ads for 9.99
