Did I Miss Something??? An Animation Window Update? 2020.2.2

In the past when creating animations on an object with children, I could select the parent object and the timeline would display all of the related keyframes on the child objects. Now when I select the parent, it instead shows no keyframes and no properties, and I have to click on children to view their keyframes one at a time, and furthermore, sometimes certain properties just won't even show up in the timeline.

This is becoming very frustrating and is causing a lot of problems with my workflow. Is there some new setting that I need to check or something? Is anyone else experiencing this issue? I really could use some help.

I'm using Unity 2020.2.2
