I am a salaryman and blogger in Japan.
When I try to watch YouTube on Nintendo Switch, I can’t watch it!
・It doesn’t fix even if the power is turned off and on again.
・I get an error even if I download it again.
When I tried to watch YouTube, the screen sometimes rotated and got stuck.

I have investigated the cause and resolved it, so I would like to share it.
Why the YouTube screen rotates and cannot be seen
Frankly, are you playing 【Animal Crossing New Horizons】?

If you change the game time, you will get an error on YouTube.
If you are playing Animal Crossing New Horizons, you can solve it 100% by the following methods.
Since YouTube is a time-managed medium, but if the times here do not match, you will not be able to watch YouTube.
The reason why you can’t watch YouTube is because you are changing the time of the main unit.
So, if you set the time of the Nintendo Switch itself back to the current time, you will be able to browse YouTube.
