In the platform reach section, you can fill in the links to your apps in the app store and enable Airplay and Chromecast.
The links to the app stores are used to guide the customer to download the app if they enter your website on a mobile browser.
While Airplay only needs to be enabled, Chromecast needs an ID. You will either get the ID from us or you can get it from the Chromecast app creation portal if you have your own access.
