There will or should be a separate Premium Pass button that is different from the
Lightning Lane Multi Pass / Single Pass buttons. It should appear on the Main Screen. The Main screen is reached by taping the 3 horizontal lines on the bottom left of any of the navigation screens in
MDE. On the Main screen just press the top right tile marked Lighting Lane Passes.
The LLMP, LLSP and LLPP all should show up on a screen when you press the top right tile marked Lighting Lane Passes. The Premiere pass button will only show up if you have a valid linked on-site reservation.
If you have any problems finding the Premiere Pass button you can always uses the search feature to find the Premiere Pass landing screen.
