Yoast Issues

Hello all.
I downloaded yoast yesterday, did the simply wizard. Did some seo on the home page, and some on-page social for Facebook. I tried to change the seo title and on-page facebook image but the changes are not being applied even when I update to save changes. when I send link over facebook messenge old seo title appears with the old image. It’s been almost 24 hours since I made the changes.

Any help and advise would be great.

Zac
