I have a mobile service coming up (I'm finally getting around to getting the couple delivery issues fixed after almost a year) and so I threw in a cover plate. I have an 8/2020 build so I'll see if the covers look the same. Or feel the same. Even if newer builds are easier, it could be some change in the bumper piece itself and not the cover.
I'm probably gong to try
this mod with the old cover.
