PopUp Pro Approximate URL stopped working

I have a site creation workflow that does the following:

1. Creates a site using custom forms
2. Makes a copy of a site using New Blog Templates
3. Takes the user to the login page and displays a welcome message using PopUp Pro

The popover was displayed based on two rules:

A. Only display once
B. Only display if on this approximate URL:

/student-login/?notification=newsite

Unfortunately, while it was working previously, I'm now not able to get it to work on the approximate URL. At this point, I have disabled that condition and the popover is now working as expected again.
