On some older apps and devices (like an old version of the YouTube app), you may see a 'This action isn't allowed' message when trying to create a channel.
If this happens, it means that your YouTube app is out of date. You can try one of these options to create your channel:
- Update to the latest version of your YouTube app and try again to create a new channel.
- On a computer, create a new channel on YouTube using a web browser. Then, sign in to the channel using the app on your mobile device.
