That's great to hear! Is this with the shades and paint, or something else?

Pretty sure it's in-house developed black paint.

Black paint was causing heat problems.

Sounds like it's more about orientation:

SpaceX has responded to the concerns of astronomers by developing an improved reflective layer for their Gen 2 satellites which directs more of the sunlight away from observers on the ground.

Cool!

Mirror film. The antenna have a highly reflective film coating that reflects all light from the sun in a specific direction in space, away from Earth. The parts of the satellite that aren't flat enough for the mirror film do use the dark paint.
