Featured Image Not Showing in Wordpress Reader

Hi everyone; I hope all is well.

Somewhat of a strange problem. For the last couple of weeks, the lead/featured image for my blog posts is not showing in the WordPress Reader. Every post I make has a featured image, and the image is showing across social media and in the post itself. Up until two weeks ago, this was working fine. Nothing has changed on my end of things. Any ideas why it’s not showing in the reader?
