I create a accounte on pc for restarte the game so im not lost, but i was thinking about trade the item i got on my switch to my pc so go to the dojo on my switch and create a trade things i wait 1 day for finish the build and i try to trade it says that i need the A2F (i turn on the cross  platforme option) after that i try to trade and it says me that inneed a cross-plateforme save soo i go on the website and i try to creat the link but when i try to link it it says me to choose a main account so i choose the pc but it says me that the progression and item i got on the account i try to trad will be delete soo i try to creat me a playstation account for the cross-plateforme save and when i try to link it says me to connect on a playstation (i dont have one...) soo the deal is to delete the acounte where i have all my valuable stuff for trade with the account where all my vamuble stuff are. And i dont want to delete the pc account becaus i dont wan tto restart the game again. So what i need to do for trad my stuff ?
