wow, just wow!
It showed unconnected web ide so I was not sure what am I supposed to do but then I just bravely pressed upload and it magically connected, uploaded and run! Only then I checked article and it clearly suggests to click connect so definitely my fault :-)
And BTW when I click disconnect and then connect again I see initial Espruino logo text output (which is not shown first time), then red "Unable to retrieve board information. Connection Error?" and console cursor blinks but no entry is possible.
