I am trying to update my imdbpro page but it keeps sending me to my daughter's page that I also managed

Hello hello Nannette,

I have checked the account associated with your email and I see that you are claiming your daughter's page.
On the other hand, your page has not yet been claimed.

In this scenario, you have two options:

1) You can unclaim your daughter's page and claim your own.
2) You can create a new membership and use it for your page.
