If you click Join on the AT AT screen before 7 am, it will take you to the screen that says "This virtual queue is not currently enrolling additional Guests." You would then need to either go back to the AT AT screen, or refresh the second page. Either way, you lose time.One thing is confusing to me. Do you have to click join three times or two once 7am hits? Some people are saying wait at the AT AT screen till 7 then hit join (3 times). However, you can hit the first join (the AT AT screen) early at say 655. Then from the screen it brought you to at 7 a join button pops up. You hit that and then join again (the select part screen) and then done. There is no reason to wait till 7 to press the first ( ATAT) join right just do it before so that at 7 you only have to press join twice?
If you time it right, when you click on the AT AT join button, the next screen will have another join button. Too early and that second join button will not be there - and you are screwed.
