Contact Us popup not allowing viewing of closing message at the end.

Why is the Contact Us form a popup window now if someone has a custom domain?

After someone submits the contact us form, it doesn't let them read the final "Contact Us Form Closing" message at the end since it just closes the window.

My friend said she can't even get the popup window to open since she has popups blocked.

This is so strange. It was better before this change. Can we turn it off?

We had to remove google captcha protection as they are now charging for its use.
The work-a-round for cloudflare requires a popup to be used.
Is it really important to read the after submit message if so I will look into increasing the time before it closes.
She must have very aggresive settings on her blocker, which one is she using?
