Microsoft has backed “Fortnite” video game maker Epic Games in its legal battle with Apple – alleging in a new court filing that the Tim Cook-led tech giant has “stymied” its own efforts to create an Xbox mobile store.

The problem is that Apple is specifically not allowed to “prohibit” the use of external payment links. It can reject apps, or ban developer accounts, at its own discretion.
