Nintendo Japan has announced the termination of the YouTube app for 3DS on September 3, 2019. The application will also be removed from the eShop on this date.
It is very likely that the announcement concerns all regions. Only in May we reported that the app does not work at all and crashes right at the start.
The mobile website for the New Nintendo 3DS, as well as the Wii-U and Switch versions are not affected.
