I referred to the (press) spokesman for Belgium, he is on Twitter but
since he is not a support line in any way, I won't share his details
here. It's not like he answered my message either, it just struck me

I've sent a message to the Belgian Google spokesman on Monday. Not sure
whether it is related, but today my Google hub listens to the usual
shopping list commands again. Problem fixed!
Frustrating indeed, this is a perfectly handy function and they've
ruined it! Shopping lists in Dutch always respond with recipes. I really
hope this is fixed soon.
