The very first thing you need to do before using the Virtual Queue is to download the My Disney Experience app on your mobile device.
Every second counts, so one trick that will save you some time is by pre-selecting your party before trying to get a boarding pass.
Before the distribution window opens at 6:50 am, ensure your internet connection is working by testing it with your browser. This gives you a 10-minute head start to prepare.
Make sure your account is properly logged into My Disney Experience as it sometimes logs you out automatically.
This could easily happen to you because boarding passes usually sell out in seconds since they are the only free way to ride.
