Hi @selftripsru
Note that the “insert to post” button you are referring to belongs to the WP media library and not Cloudinary’s media library.
When using our plugin and going to Cloudinaery’s media library, there are additional options that you could do.
In order to insert a resource from Cloudinary’s media library to that of WP you need to click the orange insert button on the top panel as seen in this video.
You would then be able to insert that resource from WP media library to the post
Let us know if that helps
