Complete your sign up doesn't appear after accepting invite from email

After starting with the Nextjs CSM template, I waited for the site to deploy and then accepted the invite from no-reply@netlify.com. My site opened but I never see the popup to create a password to complete the sign up process? I’ve tried on multiple browsers and have disabled “block popups”. Any advice?

Make sure you go to a page that has the Identity Widget added to it: GitHub - netlify/netlify-identity-widget: A zero config, framework free Netlify Identity widget with the confirmation token in the address bar.
