Hey Jack,

Apologies for such a late reply and sorry to hear that you have issues with linked accounts.

Please keep in mind that at the moment we can only respond to players' questions in the English language.
We can translate non-English messages via an online translation tool, however, if you would like more players to engage and respond to your thread, we would advise you to post your future messages in English.

We cannot assist you with unlinking your Ubisoft account via Steam forums, sadly or with any other account-related issues.

Please submit a support ticket to our colleagues, who will be able to help you:
Contact Us.[www.ubisoft.com]

Please remember that by linking a different Ubisoft account to your Steam you will lose all progress made on the old account, and possibly more.
