On login, redirect the user back to where they were

I don’t believe that will work:

Redirect Action no working with NodeJS

If you have a redirect action step in a server action, then it will redirect that page when executing that step. Redirect only works when that page is loaded with the browser and not using ajax. The ajax can follow the redirect but it doesn’t update you page in the browser. I think that you had linked it in PHP and did not call it via ajax (server connect component).
