This issue is definitely not resolved.
We are running WPBakery with a customized Impreza theme. I do not want to disable all plugins. Maybe I will switch back to the basic Storefront for testing but this will temporarily kill most of the pages on our site.
I can tell you that if I refresh the browser page your Alert form actually appears and them immediate disappears. Does this help you?
As you can see I am not the only website with this problem.
