Changes are not reflected to the published document

When I do modifications to this document, it is not reflecting to the published document, unless I unpublish and publish again.

Any clue why the published document is not updated when I refresh it?

Dear @Mohamed_Essam ,

I catched myself lately in a similar situation.
It came out that I changed the link to the published doc.

Therefore copy it again, make a change and open the link in a private session of your browser.

Rather sure, you will see the update reflecting.

Otherwise you might want to contact support to have a look.
