The replay timeline isn't visible either inside the Oculus headseat or on the desktop when the game is paused. I can sometimes click around blindly and activate the timeline, but I have never been able to click the "play" button this way (believe me, I've tried many times). Would love the ability to watch a replay after making an awesome landing! Using Steam Oculus VR mode (vers. 2.01EA3.30).
