Glad you got a resolution. Google recently banned my ad account for running ads to my landing page templates and I still don't know what was wrong with that. They just gave me a bs corporate answer and that was it.
I’m so sorry this happened to you. Can you show us the site?
I just ran ads with headlines like Nextjs + TailwindCSS Landing Pages
Apparently somehow I ran afoul of their Circumventing Systems policy. I don't know how this qualifies and when I appealed they came back saying the same thing.
