Diana,
Thanks very much for your reply. Restrictions are off on my phone.
Your reply forced me to look again at my phone. I had known that instead of "Password Settings" my phone displayed "Touch ID is enabled for all purchases", but apparently I didn't understand the significance of that statement. When I turned off Use Touch ID for iTunes & App Store then the Password Settings button magically appeared.
I don't understand why one can't access Password Settings if Touch ID is enabled. Is "required" more appropriate than "enabled"?
Peter
