NopCommerce version 4.0
Downloaded the plugin for Google Shopping (16920_1030_GoogleShopping.zip)
The views included with the Source Code version do not display any content when on the Configure screen.
The views included with the no source version (binaries), are correct.
If you compare the Configure.cshtml view between the one included in the source code folder and the view included with the binaries folder, you will see they are different.
I was able to get the configure screen to render properly by copying the views files from the no source folder, however, I don't know if there are any further issues that may be less obvious.
