Q: terms and condition button missing on ios app store for iTunes

Hi lostlins,

Welcome to the Support Communities!

First, I recommend restarting your phone and then resetting if it's still not working:

Restarting your device

1. Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
2. Press and hold the Sleep/Wake button until the Apple logo appears.

Note: Reset your device only if you are unable to restart it.

Resetting your device

Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.

If you can access your home screen, I also recommend verifying that cookies are not blocked and private browsing is turned off in Settings>Safari:
