I am unsure if this is just a terrible oversight by QA, or something Sony mandated; but apparently, if you log into Fortnite on PS4 at all, you will then be unable to use your account on Switch.

That seems to be an issue with Fortnite itself. I don't see how Sony could stop anyone from logging on Switch on a game that belongs to a third party. At best it's Nintendo that should be blamed for not letting people on THEIR platform log on a game for whatever reason.

But I don't even think that's the case, it must be a purely Fortnite issue because I assume the account you can't log on is a fortnite account and not a Sony nor Nintendo account.

Here are the messages you get when you try to log into an Xbox or a Switch, with and account that logged into PS4.

"This Fornite account is associated with a platform which does not allow it to operate on Xbox. Neither the Fortnite website or Epic Customer Service are able to change this. To Play Fortnite on Xbox, please create a new account."

or

"This Fornite account is associated with a platform which does not allow it to operate on Switch. Neither the Fortnite website or Epic Customer Service are able to change this. To Play Fortnite on Switch, please create a new account."

The general consensus across the entire internet is that it is Sony's fault. The only time the issue ever comes up is if someone tries using an account that has logged into a PS4 at some point. Never when dealing with any other system, PC, phone, ect.
