Cache Not Renewing when a Post is Published

A user pointed out that our blog wasn’t showing current posts. I cleared the WP Fastest Cache and all was good. I then published another post, which didn’t show up on the user’s browser. Checking with a second user, revealed the same results: the new post didn’t appear.

I did see the new post, but then I was logged in and had the settings NOT show cached pages to those logged in.

I deleted the cache and disabled WP Fastest Cache, and my customers are seeing the new blog post.

I don’t know if this is a bug or a plugin conflict, but I wanted to bring it to your attention.

I’m using Version 0.8.8.1 of WP Fastest Cache and WordPress 4.9.6
