Premium Not Authenticating: 404 Redirect After APIExperts

This support ticket is a follow up to my email/Jira support ticket (WPEPSUP-1583) that I have not gotten a reply to since 24 October.

When attempting to authenticate the paid, premium version of WP EasyPay, I follow the steps provided in documentation and the screenshare video provided by the team.

However, once I reach the APIExperts.io “You just authenticated Square!” confirmation screen, the “THAT’S MY SITE – REDIRECT ME” button points me back to a nonexistent page on my site, which gives me a 404 error. The Square account is not authenticated or activated, even though preceding steps state that it is.

Please see my support ticket for my provided screenshare video.
