My Smart lock option has disappeared?

[Android Central Question]

I was using Smart lock so I didn't have to keep unlocking my phone while I was at home or while it was on me.
I went to change the length of time it took to lock my phone. However, it wasn't even there.
Has anybody had the same issue and did you find a fix?

Personally the option for Smart Lock disappeared when I added the Corporate Work Email to my phone.

Both Mobile Iron and Microsoft Company Portal remove all Smart Lock options if your company sets the policy to do so.

My smart lock disappeared this morning. It's not listed in Privacy (Security) (Android 7.0) but it is still listed in the Trust Agents section, in Settings.
Relevant? Just yesterday I opted out of reviewing suggestion of places I have visited via Google Maps.
Googled many times for an answer but all directs to finding Smart Lock in the Privacy section of Settings and it's listed in my phone (LG Aristo).
