Epic Games, the creator of "Fortnite," announced on Friday that Apple (NASDAQ:AAPL) has obstructed its attempts to launch the Epic Games Store on iPhones and iPads in Europe, marking a new phase in the ongoing dispute over Apple's control of the iOS app ecosystem.

According to Epic, Apple has rejected its application twice, citing issues with the design of buttons and labels in the proposed store, which Apple claims are too similar to those in its own App Store.

Epic countered this claim, stating, "We are using the same 'Install' and 'In-app purchases' naming conventions that are used across popular app stores on multiple platforms, and are following standard conventions for buttons in iOS apps."

The company has voiced its frustrations on social media platform X, labeling Appleā€™s rejections as "arbitrary" and "obstructive," and has reported these issues to the European Commission, alleging violations of the Digital Markets Act (DMA).

The conflict between Epic and Apple began in 2020 when Epic sued Apple in the U.S., challenging the up to 30% commission on in-app payments enforced by Apple on iOS devices as a violation of antitrust laws.
