The Epic Games Store app for EU iPhones has passed Apple’s notarization process, putting the alternative app store a step closer to selling apps directly to iOS users outside of the App Store. AppleInsider reports that while Apple confirmed the app had passed, it has asked Epic to “fix the buttons” in a future submission to the company’s app review process.

But the approval is just “temporary,” posted Epic CEO Tim Sweeney, who puts Apple’s request differently. He says the company is “demanding we change the buttons in the next version,” vowing that the company will “fight this.” The apparently conditional approval is just the latest part of the back-and-forth saga between Apple and Epic. Previously, Apple reinstated Epic Games Sweden’s European developer license after EU regulators started investigating its decision to pull it.
