The extension license should automatically change to the Full license after you purchase the extension. If it did not change the license automatically after you purchased it then please try these steps in a row:

  1. Make sure that you are signed into the browser. (On the upper right corner of the browser click on the Profile icon 👤 . Sign in with your email account.) Make sure Sync is on.
  2. Click on the extension icon. Scroll down to "License Key" or "Order ID". You may need to enter your order number or license key that was emailed to you in the "Order ID" field.

    Click on "Check". If the "Sign in with Google" screen appears then you must click on "Allow".

  3. As a last resort you may need to Reset Chrome. Follow the instructions to Reset Chrome at https://support.google.com/chrome/answer/3296214

    When Chrome has reset then make sure that you first sign into Chrome with your Google account. Make sure sync is on. Then reinstall the extension from the Chrome Web Store and follow step 2 again.
