If you have recently installed a tracking extension onto your WooCommerce store, you may find that you still receive a "Tracking Extension Not Found" message within your WooCommerce settings.
In order to solve this, there is a simple fix within your WooCommerce settings. Navigate to the bottom of the page to Advanced settings, and hit the Refresh Tracking Providers button.
Doing so will force a check for an updated list of tracking providers, including WooCommerce extensions, and your extension should appear right away.
