WP SEO By Yoast Unable to be Updated by Pro Site User

Hi Guys,

Seems we are having an issue where the a customer / Pro Site user is unable to modify it's yoast settings.

When we login from admin it works well and we can update it for the client, but the client logged in can not change any settings or any page tags by themselves.

Can you please advise on what we are doing wrong and what is the solution at the earliest?
