Skindigo Installation issues (SU2019)

After I’ve opened extension warehouse in SketchUp and found the extension I want to download, I click the install button and a loading page comes up and then never changes. Just stuck with it saying loading and I can’t install anything.

3D warehouse is working fine.

I specifically want to download Skindigo and have tried downloading it separately on their website, but then get stuck on how to add it to the extensions manager.

EDIT: Just realised it’s not compatible with SketchUp 2019!

have you checked the website?

I’m using it with 2019, so it’s compatible. Did you download the installer for Indigo combined with the Sketchup version or only for the plugin itself?
