Can Fortnite still be played on the PC when the account is connected to Nintendo Switch?

My little brother has bought a Nintendo switch today and now wants to play Fortnite. Since I do not play so often with my account (PC), I wanted to give him the acc now, but I still want to play occasionally on the Acc. A friend playing on the Playstation. But then could not play on the switch anymore. Is this synonymous s.PC, or is it without problems?

No. This problem only exists with the PlayStation because Sony did not allow it.

On the epicgames page you can link an account under Account> linked accounts (or something similar). For example, I have an account for xbox and switch and I will soon be synonymous for the pc link
