Thank you Sir. This did solve my problem. But, I didn't even know about the Screen Time option in the Settings menu and therefore, did not restrict the Content & Privacy Restrictions. It must have been either the default position when the IOS update was installed or changed as a result of some other operation within the multitude of options in Settings menu. I did not specifically change that particular option within Content & Privacy Restriction. In any event, your suggestion worked and for that I'm happy. Also, I had to delete my fingerprints and redo them before the Touch ID would work properly.
