Since updating, I can no longer enable Touch ID for iTunes/App Store in settings. Has anyone else noticed this? I did reset all settings and network settings followed by two restarts.
Could it just be that you had to login once after rebooting from the update? After rebooting, you have to login with your password to reenable touch ID for the app store, but since you put in your password, it won't make you authenticate right after with your fingerprint.
