App Store

I had recently deleted the app “instagram” off my iPhone. When I go to App Store to try to download it again, it sends me to something that says “ verification required” when I put in my password, it just sends me to my billing info and I push ok so it updates it... but still won’t let me download it and goes to the same thing every time. I use to just download apps and put in my Apple ID password. Don’t know why it’s bringing me to this and still won’t let me download the app
