Hi all -- I'm just starting to try to use the KendoReactFree components to see what the library is like. I'm starting with the Grid component -- I know it has both free and paid elements, but even in with its simplest configuration, I'm getting an error banner saying that I need a license: 

License key missing for KendoReact v12.1.0. A license key is required for both paid and trial usage. Learn how to set up a license key.
See the browser console for a list of Premium features currently in use.

The message says that I can check the console for a list of Premium features in use, but the console just says I need a license -- no list of features. I'm using the sample code from your website: 

This is the whole code:

import { Grid, GridColumn as Column } from '@progress/kendo-react-grid';
import products from './products';
export default function KendoGridPage() {
  return (
    <Grid data={products} />
  );
}
Should this be getting that banner? What Premium features are in use? Is there something I need to do to invoke the free usage? 

Thanks

Hello, Ken,

Your assumption is correct - no license is used for the shared setup and you can freely use the free features of the Grid without adding any license. It is required either for using the paid features, or when trying them with a trial license.

For convenience, I am attaching a test sample containing the shared Grid setup where no license is added and no watermark is shown. Can you test it and see whether it works as expected at your end as well? Does it differ from your actual setup somehow?
