How a company can create a world as incredible as Star Wars Galaxy's Edge but such a terrible app is beyond me. For some reason, the app always defaults to Magic Kingdom even if you clearly have reservations to another park. The park maps are barely usable, and ride wait times are all over the place. Lightning lane selections aren't held for you so may change or not be available until confirmed in the app. The only solidly reliable part is the mobile dining order which I highly recommend doing.
