Hi,
Thanks for reaching out and thanks for using Crio Pro WordPress theme!
I inspected your blog page and it looks like the first post actually does display the “read more” tag. See screenshot here.
It’s possible the Read More tag might not have been inserted properly on the second post.
To double-check, switch over to the Text editor tab, and look for the tag (possibly at the very end of your post) that looks like this:
<!--more-->
You can cut the tag out and paste it where it was meant to be placed.
I hope this helps.
