It is the mobile version of a website so it might behave strange on desktop. When I'm on desktop I can use the standard version of the website and then clipping works fine. So yes, I can always wait untill I'm on my laptop to clip the page but I would prefer to also have this functionallity on my mobile device.
Doing further research I found out that on the Samsung browser clipping the full article on this website works as intended. I noticed that I got a cookie consent page first in this browser when going to this site, before I shared to Evernote. So at least I have a workaround.
