This is a pop up ad whenever I’m navigating sites with heavy ads that redirect you. The thing about this one is that it creates a prompt for you to call the number on your iPhone, but keeps sending that exact prompt OVER AND OVER to the point where you cannot cancel it. You can’t decline it or get out of it. You can’t go to your home, or do anything, the only option is to hard restart/reset your phone (pretty malicious strategy if you ask me). Link to image is https://imgur.com/a/KOklzuN and the phone number is 1-803-795-1726 . I can’t provide a direct link since I’m on my phone and goes on that site basically blocks me out from doing anything on my phone. I took a screenshot before I had to restart my phone.
