Is this a bug?

My store has a combination of grouped and simple products.

I have created a google feed, when I select the "Export Grouped products" option only the grouped products and not the simple products are exported. If I deselect it then only the simple products are exported.

This means I will have to maintain two feeds of every type to export all my products. I would have thought that if this option is selected then both simple and grouped products would be exported.

Is this by design?

This may be a licencing issue (my site is reverting to the trial mode), I have sent an email to support also.

Was the problem solved?

Yes, it was a licencing issue. All products are being exported now, thanks.
