with how light works and the constant expansion of what we term the “observable universe” why don’t we constantly see new stars appearing in the night sky as the observable part expands and stars/galaxies light reaches us for the first time?
The night sky has stayed relatively the same (accounting for changing postions over time, stella phenom, supernovas etc.) for all of humans written history.

Because of the way light travels.
Anything that’s outside of the observable universe we will never see.
Expansion of the universe doesn’t mean we’re seeing more and more it means that the stuff that we can see is spreading out and some things are moving out of our visual range.
Any star that doesn’t form inside of the observable universe we will never see
