Planar Reflections + Lumen Lighting deprecated? 5.0 to 5.2

Hey folks. So in the game I’m working on we have a mirror for a brief moment in the game. In our previous UE5.0 project I added a planar reflection and used a Post Process Material to switch the Reflections to “Screen Space” which would activate the Planar Reflections while not having to change the Project settings GI to “screen space”. This would yield a near perfect mirror reflection.

Now in 5.2 this same exact setup is not working. The reflections when set to Screen Space in the PP are yielding very streaky and awful reflections. And the Lumen reflections do not look very good either.

Can someone confirm if Planar Reflections + Lumen is deprecated? And if so, how it would be possible to get a perfect mirror reflection in 5.2?
