The steps for confirming a customer on this Learn article are not happening on the "pop up" step. There is no "account confirmed" pop up anymore. Instead, it just brings the customer to a pop up with the account page on it.
For example, going to
Detailz Boutique faceBook page: https://www.facebook.com/detailzboutiquenm/
Send a message to the page with the word Register. I get a response with a "Log In" button, but clicking it will bring up the account page in a pop up window. I click Confirm there to confirm my email address. But I am not confirmed yet. I have to click Get Started to confirm on the page.
According to Learn, it should be a pop up that says "Account Confirmed" with a check mark. That doesn't appear.
