I bought MW19 during the sale on steam and I first played it on a random account just for the campaign. I remembered I had a stacked account and I tried to unlink steam from the random account to then link it to my main but it keeps showing up an error. I've tried unlinking on pc, phone, in incognito, I also tried linking a battle.net account to it and then trying to unlink steam but it doesnt work at all. Does anyone have a solution for this?
