If I remove my Psn account from Fortnite, can I add the same Psn account again? And would the progress (skins etc.) be on the Ps4 account or on the Epic Games account?
You have to go to settings and to the last page
Skins are saved on the Epic account and not on the psn account
Okay, the battle pass too or just the skins?
All your data. The psn account only provides your display name
