NO MATER HOW MANY TIMES I’VE DOWNLOADED ENSCAPE NOTHING IS SHOWING UP IN SKETCHUP PRO 2020!!!
We do not officially support SketchUp 2020 yet, but will very soon.
There is a workaround mentioned here you may wanna try, but we cannot guarantee that it’ll work without problems, nor can we offer official support for this version used with Enscape yet.
