Topic: Youtube website is not working on the Wii U!!!

Is there a way to get Videos playing through the Gamepad as they only seem to show through the TV for me.?

Try this Nintendo Life article.

Sorry, i mean through the Youtube app not the browser. Or can you only search videos on the gamepad through app?

The workaround is useful but it really is a sticking plaster. The dialogue should be focused on one of direction action, lobbying YouTube and Nintendo, making them aware of the problem and demanding that it be fixed.

If you'd like to contribute then go to the YouTube website on the Wii U Browser, select 'Leave Feedback' (bottom right-corner) and air your grievances. Otherwise I fear nothing will get done at all.
