I am glad the app worked for you guys. I tried the app in MIA and it did not work for me. I questioned the immigration officer at the booth and he told me I had one of those names that would have to be cleared every time. I have a very common first and last name. He said the app would never work for me and I would always get an X at the kiosk. He told me the only alternative I had was global entry. I now have GE.
