Links to YouTube videos don't open in the YouTube app but as the web version - Feddit

I checked what kind of links are tied to the YouTube app and it’s alle the usual links for YouTube (Youtou.be [http://Youtou.be], Youtube. com, etc;). Yet, I click on a Yt video link and it opens up a browser window. I didn’t change anything, whether in the options of Voyager nor which links should open with which app. Any idea what is going on?
