Just tried and worked for me via Google. I have noticed previously that you need to click on the link, not right clicking to open it in a new window/tab. You might also need to make sure your browser is sending the Referrer and you don't have a privacy extension or similar extension / Do Not Track blocking it.

(This time I tested was on mobile and clicking on the AMP link in Chrome Android, but I haven't had problems with it myself on desktop beyond the new-tab issue.)

Try turning off your adblocker for WSJ.
