Since Marshmalow update I have NO Application manager

[AC Question]

I have had no application manager on my LG G4 since the Marshmallow update. From what I have seen other other peoples phone it should be in Setting.> General> Apps and then a dropdown in Apps.I cant find it anywhere. I have tried resetting to factory setting but that doesnt let me go back to Lollipop.
Help . how do I fix?
