I have created a partner access account to ancestry but ancestry only shows as a paid membership. I can not link and connect my family search account to my ancestry account.
I have private message guest with this link
You may wish to view the Support Center in Ancestry which shares information on how to identify your account with familysearch and share that information with Ancestry. https://support.ancestry.com/s/article/Church-of-Jesus-Christ-Ancestry-Membership
