What's wrong with my usage of Azure Alerts?

Question

OK, so I simply want to create an alert, for when my URL is unreachable.

As a test, I followed the steps found here to create an availability test for https://www.google.com , and as success criteria, I put 500 as my HTTP response; it was felt that this will trigger an alert.

The action group that I created is an MS Teams group; this is working, I know this because it is used by different alerts. Then, I created a new Alert, with the Condition of my newly created availability test, then I waited.

I expected to get an alert upon failure of my test. I can see that the test is failing, but there is no alert. What might I [not be grasping/be doing wrong]?

Turns out I must have mistyped something. All I know is that doing it from scratch (for the 3rd time) fixed it.
