Description of problem

I'm attempting to advertise my site via facebook and twitter (mostly twitter). When I put the link for the site and it gives the site preview which has the site description it hasn't updated. I corrected some typos but they don't show up on the site description preview in the attachment. Is there a way to fix it?

Hello,

How long ago did you do the update? Sometimes it can take a few days or weeks for your changes to update on search engines and social media.
