[2021] [Download/Installation]Not logging on to other ubisoft account

Hello all,

I have played on steam for about a year now, and just got siege again on sale on the epic games store for using my alt account for fooling around with friends. Previously my main ubisoft account was linked to my epic account, and I cannot seem to find a way to unlink it at all so that I may access my other account. Please someone help!
(this post is on my alt account)\

Thanks in advance!
