If you feel you’ve performed all the configuration steps to deploy your chat widget, get it will not appear on your site, try the following.
-In google chrome click on the three vertical dots on the top right corner of your browser window.
Choose the option “New incognito window”. If the tawk.to chast app appears then you are most likely blocked by a browser extension.
In my case Malwarebytes was blocking the chat app. When I added my site to the white list in malwarebytes I had no further issues.
