I have been a spotify premium subscriber for going on seven years. I just signed up to the Hulu add on (w ads) earlier this year.
After I updated my credit card details on spotify, my Hulu account is gone. Poof. Disappeared.
Spotify support tells me that since the Hulu add on registration has closed for new subscribers, they can't link my premium to my Hulu again, even though I WAS registered before it closed. They said to post here for a solution.
