How do I know if it has worked?

Hello,

for my blog https://jesandbleu.com I noticed my images (from featured images) weren’t showing up on Bloglovin’, so I installed and activated this plugin.

I’m just wondering if I am supposed to see any difference in my post? (when I go to edit my post) because I don’t see anything changed, and I know that it will take up to 24 hours for my featured image to show on Bloglovin’.

How do I know if it has worked?
