Apple previously stated they would terminate “Sign In with Apple” support for Epic Games accounts after September 11, 2020, but today provided an indefinite extension.
And this Fortnite Tweet:
UPDATE: Apple previously stated they would terminate “Sign In with Apple” support for Epic Games accounts after Sept 11, 2020, but today provided an indefinite extension. We still recommend you prepare your accounts now for “Sign In with Apple” removal. https://t.co/T0Rq0tfrR7

Did Apple reverse course here? Or is there more to this story? One likely result is Fortnite users switching from “Sign in with Apple” and moving to an email account-based login. Which gives Epic more user data.
