If you are cursing your life trying to figure this out, here is the actual how to (you cant find anywhere from McDs):
Once you load the app
-scroll to your cartoons general picture
-tap "see games"
-tap "scan toy"
-tap "scan your toy"
Then it will unlock the particular game you were trying to load. Why does it have to be this hard? I have no effing clue.
McDonalds, if you want to piss people off make a tutorial of "simple" directions stating things like "turn on the lights", "use your camera" with no mention of how to ACTUALLY GET TO THE SCREEN FOR SCANNING!!!! You have successfully over explained every element, after claiming to make things more "simple" multiple times.
-The home screen is WAY overcrowded with extraneous images.
-The "parents" tab tutorial is complete crap.
-Hire an actual UI/UX designer.
We all know you have the cash. There is no reason in the world this has to be so terrible. I mean. Really. So so so awful.
