Troubleshooting activation issues on yt.be/activate involves several steps.
First, ensure you have a stable internet connection. Next, verify that you're
entering the correct activation code displayed on your device. Clear your
browser cache and cookies, then try again. If the problem persists, use a
different browser or device to complete the activation process. Ensure your
YouTube app and device software are up-to-date. If none of these steps work,
check the YouTube Help Center for specific troubleshooting guides or contact
YouTube support for further assistance.
