Yoast eye icon not highlighting suggestions

This is an official guide from WP: https://wordpress.com/support/wordpress-editor/switching-from-the-classic-to-the-block-editor/

Hope it's helpful :)

but yoast works in classic editor and not block editor and I have already developed 5 sites (in one multisite installation)) with different layouts done from your site library which none of them works with yoast

I really don't believe this is GP related issue.

Any chance you can check with Yoast's support team for their comments first?

Alternatively, you can start a staging site and test this in a fresh GP install and a fresh default Twenty series theme install.
