The prettifier uncenters centered LaTex lines.

[SkepticMystic]

One can use $x + y$ for inline math cells, but use $$x + y$$ for centered math cells. These each serve their own purpose. But when running the prettifier, centered math cells are change to inline cells

Same here, when I intended to have the display math, this prettifier always revert it to inline math...

You could use line breaks to solve this problem
