I see this in the console when I click the "choose time slot" button:

Uncaught ReferenceError: cmCreateElementTag is not defined

This is Eluminate. Our shim doesn't stub out this (and many other) functions in Eluminate, but making it a no-op seems to suffice for this site, so it seems like a simple fix.

The URL was no longer valid, but I found a different on: URL: https://www.boots.com/health-pharmacy-advice/vaccinations/meningitis-b
The issue is fixed, "Time slots" popup is triggered now.
