I bought this morning on the Xbox the Gipfelstürmer package for 4.99 euro, but have now looked at the PC and there are no vbucks and no skin there.
Yes the accounts are linked.
It should be noted, however, that I have no Xbox Live on the Xbox that means I have bought the package in the store and I fortnite after the purchase on the xbox have not yet started on the xbox.
You have to have xbox gold. Because you have to download the purchased product and activate it in the game by STARTING. Have fun.
