Due to the 410 update, you will have to open a new save to play.
The previous version menu for selecting tasks has been removed and you need to perform tasks in the following order:
City mission → Pyramid mission → Druid mission → Amazon Island mission, and after completing the Amazon Island mission, you will automatically be given the application for the Wizarding Academy (the previous wizarding Academy application task has been deleted), and you can officially launch the Wizarding Academy mission.
