Need help post sharing

hie guys
i was testing my app to see if i can share posts on social media apps and see whether my post will appear the same. I tried sharing one on facebook and this is how it appeared. im using the AddToAnyShare Button. Am i missing something or is it because im not yet on a paid plan. what appears is a link to website

Yes. You need to be on a paid plan to update the SEO meta information of your app.

THANKS for that
