I'm going to move you to Hints.
If this is a Glitch, there's nothing we can do about IOS problems.
But I suspect it's a Hints problem related to you knowing what to do but George not knowing what to do. If a walkthrough tells you to do something, but you don't get that information from the game, the game may not let you use the information. Did you previously get any comment from George about what location to use? Maybe you have to keep clicking on something until George gives you a comment.
