Because you can't reply to the review, this is a note for the manager:
I have used the app twice to get on the list before arriving. First time the incident I mentioned in my first review occurred. I tried it again two weeks ago and then called the hostess stand. Person I spoke to said it takes 10 minutes off the wait max and he couldn't even see if I was on the list. We went somewhere else that night. Just wanted to make you aware. Thanks!
