The use/function example you provided, and the accompanying screenshot, is dated April 2018. That is all I was referring to, and that was never unclear in the least. You can draw your own conclusions there Jarek, this is now a 4 year old disaster. The time for idle talk about use and function for products that don't exist/never shipped has long since passed. The only information anyone now seeks is status and details on production and shipment, or refund.
