It has not been announced yet when the new Genie features and the new processes for
DAS will become active. It may be soon, or some people are guessing it may not be ready until mid-October. If it’s not active at the time of your trip, you will just go to Guest Relations to register for DAS like previously.
The Genie features will be part of the My Disney Experience app for smart devices. You can get it in the Apple or Google Play App Stores.
If you don’t already have the app, you can download it at the
DISNEY website page with links to app stores
People are guessing that the new Genie features will come as an app update, so once you have it installed, keep checking for updates. I’ve read a couple of comments from people who think the DAS video sign up will be arranged from a link in the My Disney Experience app after the update.
