This is a horrible issue/bug Adobe needs to fix it IMMEDIATELY. With so many teams working remotely, this feature is imperative. My manager and I have lost time on both ends trying to figure out annotations that I can see in the review panel but they are invisible/do not highlight within the actual document to show where those actual edits go.
