Should they change the cooldown time at the accounts connect

I have a battle.net account and I connected my playstation and my pc to it. Yesterday evening I wanted to conncet my nintendo account to it but it did not let me because I logged in with a wrong battle.net account. So now I need to wait 363 days untill I can try it again to loggin. And in one month I go on holiday and I thought I would like to play overwatch 2 there but now I can not.
