Default Image and default Website blurb

Hi Team,

thanks for the great plugin. I was referred this plugin by my theme support staff (themegrill) to deal with some issues I have. However, I still cant seem to sort out the issues after installing the SEO plugin. My two issues are these:

(1) I have an issue when I share my website URL – say in a text message, in an email, on a social media post etc. What automatically happens is that the latest post’s image is grabbed when that link is typed to send or post or share the URL. I dont want the latest post image grabbed but a standard image that will represent my website. Using the ALLINONE SEO I’ve set a default OG image and a default home image in the social meta and it still doesnt work. What am I missing?

(2) When I search on google using my website name, the featured post blurb comes up below the website instead of my default website description – how do I fix this?

Please help
thanks

thanks
