Website not showing properly on Social media

Hello Please help,
I have edited Jumbotron text in the Appearance >> Customize section >> Jumbotron but when i share my website on Social media then it shows the default jumbotron text of the theme.
Please guide me is there any other way to alter the text.

Hello @gaurav,

Please use the facebook debug tool and see what fields need to be updated.

This might fetch the new information.

If possible, please provide me the website link to have a look for myself.
