The welcome page is used mainly in mobile apps and TV devices. The website doesn’t have a separate welcome page but it uses the title on the login page.
Custom welcome page
Apple might not approve your mobile app if you add a link directly to your website in the footer of the mobile welcome page. We, therefore, recommend that you use the default welcome page for the iOS app and create custom welcome pages for your other platforms. You can do that by clicking on "Add custom settings".
Translating your welcome page
You can add a translation for all items on the Welcome Page by clicking on the Translate button in the upper right corner.
