Linking Vip to the actual game

Hi there,
I have a problem with the VIP and preorder Bonuses.
I preorderd the Deluxe Edition via the EPIC Launcher and then startet collecting the VIP points and spending them on the extra Skins. I no part of the progress did I ever link my Shift/Vip Account to the EPIC Account. When I start the game I dont have acces to anyof the purchased skins. The Extra Skins and packs included in the Deluxe Edition dont seem to appear ingame too.
Somebody exiriencing the same problem or am I missing something?
Thanks in advance
