On Android 8 with my Pixel XL, I had 3 button on the bottom bar, the back button and the home button on the left side of the bottom bar, and the resent apps button on the right side. With the upgrade to Android 9, the recent apps button has disappeared.
I was able to add the recent button to Taskbar as a workaround. Thank you for that.
This is actually a System UI issue with Android 9. Since Google didn't update any Nexus/Pixel tablets to Android 9, they left the tablet version of the System UI in a very broken state.
