This thread both confuses and concerns me...
I have a Galaxy S3 and I currently have no problem running the Disney App. I use it to check wait times all the time (from my home in Illinois) and have done many mock searches for fastpass availability (though the window for my actual date isn't open yet). Both as recently as today.
I'm uncertain if you're mistaken about your phone being able to run the app, or if I should be concerned that I won't be able to run it when I get there... (Even though it seemingly runs fine in Illinois).
What'm I missing here?
EDIT/UPDATE:
Hmm. I just went to the google play store and searched "my disney experience" and it does indeed say incompatible. Guess I'm running an older version of the app? Maybe? Does this older version not allow you to make new choices after your initial 3? The app itself looks exactly like the screenshots on google play, and the screen I'm looking at says, after I use my initial 3 I can make more choices using the app...
Did I get grandfathered into the new version somehow because I owned an old version, before they updated? Despite google play thinking I shouldn't be able to run it?
