SnipCart add to cart

Installed the Shop Site skeleton, it won't add to the cart, just hangs on the "adding item" popup. Is there something I need to do to get that working? No errors reported.

I think you will need to signup with snipcart and put the api key in the snipcart.yaml. Instructions in the README.md: https://github.com/getgrav/grav-plugin-snipcart

Ah, yes. When in doubt, read the documentation ;)
