Microsoft filed an amicus brief supporting Epic Games' fight against Apple over its control over the App Store.

Microsoft has blamed Apple for the delay in launching its new Xbox mobile gaming store, supporting Epic Games' ongoing dispute with the tech giant.

Apple's actions to fight the injunction from its Epic Games App Store legal fight interfered with plans to launch the Xbox mobile web store, Microsoft has said.

Microsoft says Apple's App Store rules are to blame for the continued delay of the Xbox mobile app store it announced last summer. In an amicus brief filed this week first spotted by The Verge, Microsoft expressed support for Epic Games in the company's long-running bout against Apple.

Microsoft says its Xbox-branded mobile store has been on hold thanks to Apple’s refusal to fully comply with a ruling that was supposed to open up iOS to more competition.

Microsoft puts the blame on Apple for blocking its Xbox Store launch on mobile, citing restrictive App Store policies.
