You must choose the target Meta Quest device when you create an app page on the developer dashboard. This means that if you release an app that targets multiple Meta Quest devices, such as Rift, you have two apps in the dashboard. By default, each of these apps would have their own platform settings.
App groupings enable Meta Quest cross-device development by sharing platform settings across all apps in a grouping. This can simplify management and enables you to easily deploy changes across multiple apps.

A new grouping does not contain any predefined settings, and is easy to create.
