I encounter some kind of a bug there… I made an app in which you enter the main page and if you’re not logged in it shows a popup to log you in. It works fine on firefox and safari but chrome doesn’t show the popup whatever I try to do…
The popup showed up for me as soon as I linked it. If I had to guess, you might actually be logged in on Chrome on your machine and not realizing it. Is that a possibility? Can you try it in an incognito window on your machine?
