IPhone is making me verify payment details to download a free app. Is this a scam?

My email that I used to log into my phone was hacked a month or so ago. I changed the email address linked to my phone and ever since then I keep getting messages pop up on my phone to "Verify password". I just tried to download a free app, and now it's asking for me to verify payment details? Is this normal since I just changed email addresses or should I report it?

Added (1). I forgot to mention… When my email was hacked, so was my facebook and other accounts that were connected to that email address. That's why I'm so afraid that my phone is hacked too.
