Main Paige Navigation Title.

When I set up my website I was just a photographer. So I named my site Keith J. Fisher Photography. I have since also become a writer. Wanting to broaden my audience, I wanted to drop the word Photography and go with Keith J. Fisher.com. I have changed it in the site header settings as well as in the page settings for my home page and it works everywhere except when I send the link in Facebook messenger. The Navigation Title still says Keith J. Photography. How do I get this to change? 

Hi,

What is your site url? We can check easier

FB will need time to update, if you change and post the link to FB immediately, it will still show the old one.
