App Store keeps asking for passcode instead of Touch ID on iPhone 7. I can't find the settings to change this anywhere on my phone

I go into iTunes and App Store in settings where I can usually change the restrictions from always require passcode to only require after 15 minutes or something, but now it's not there. I could do this on my 6s but I upgraded to a 7 plus recently and I really want to change the settings to where I don't have to use my passcode every time I download an app and just use Touch ID. It's getting really annoying.

Settings > Touch ID & Passcode and enable Touch ID for App Store
