This has been going on since before the Switch version came out. It's not something new, it's just getting attention because Sony just fucked over Switch owners and they're very vocal.
its nefarious
Because I believe there is no cross console support for the battle pass between Sony/Xbox versions of Fortnite either.
Before it was XB1 Fortnite didn't play nice with PS4 Fortnite account wise
Yet both let PC and Mobile benefit off cross progression
Now Switch comes into play, XB1 allows the progression to be allowed just as they allow Minecraft
Sony on the other hand hasnt
So we know that much
Now cross play is one thing. Cross progression is another thing
Something with Sony and Epic with their linking has something on the backend be a problem
Why does everyone keep saying Paragon let me tell you some info please:
Paragon could be played PS4 or PC
You could buy in game currency "Gold" with real money
The thing was PC and PS4 Gold were separate from each other
If you bought $10 on PC roughly 1000 Gold, you'll never see it appear on PS4 and the same going the opposite way
What you could was buy items, skins, boosters, that stuff became shared
I'm guessing there's remnants of something that Sony and Epic have to dole out with that's keeping from the account linking being just forgotten
Paragon is Paragon, but whatever deal was struck with whatever linking infrastructure back then, still has some legacy going forward
No one knew Fortnite BR was even a thing 2 years ago, hell there wasn't even cross progression or cross play as it warranted now with certain modes
So it might be that too
Not making excuses, but it can't just be a flip of the switch and everything is golden
