After Galaxy S7 update, Theme for lock screen and clock are gone. How do I get it back?

[AC Question]

Originally there was a simple clock widget that I added to a theme for my lock screen. Now, after the update it is gone, and looking though the options and play store, I cannot find it. Why would something I set disappear?

Welcome to Android Central! It's not entirely unusual for a manufacturer to remove or add preinstalled widget options with system updates. If it's gone, Samsung may just have decided to get rid of it.
