If the chat bubble does not show up on your website after following these steps, there are a few troubleshooting steps you can try:

1. Clear your browser cache: Sometimes, the old version of the website may be cached in your browser. Clearing the cache can help load the updated version with the chat button.

2. Check for conflicting scripts or styles: Ensure that there are no conflicting scripts or styles on your website that may be preventing the chat button from displaying. This can be done by temporarily disabling other scripts or styles and checking if the chat button appears.

3. Test on different browsers and devices: Verify if the chat button appears correctly on different browsers and devices. It's possible that there may be compatibility issues with certain browsers or devices.

If the issue persists, it's recommended to reach out to Skype support for further assistance. They can provide specific troubleshooting steps or insights into any known issues with the chat button integration.
