I was a Pottermore Beta Tester and the original Pottermore no longer exists. Sources say it was changed to provide a mobile experience (rather than a desktop), enable JK Rowling to add new content more quickly and easily, and provide the latest news on the ever expanding magical universe (The Cursed Child
play and Fantastic Beasts
movie, for example).
While your galleons and collections are gone, some of the artwork is still accessible. The Sorting Hat will return sometime in the future as well as a new quiz to determine your Patronus.
The fandom reception has been mixed. I loved the new information about the Potter family. February Fortescue has provided some excellent information about navigating the new website here.
How do you feel about Pottermore 2.0?
