Following the back and forth that has been taking place between Apple and Epic Games, Apple has finally gone ahead and terminated app store account belonging to Epic Games'. This should not come as a surprise to anyone as the company had issued the warning previously that it is going to do that on 28th August, and it has finally happened.

Which means that not just Fortnite, all iOS apps that Epic Games had on App Store will be gone.
