Porsche removed the controls from most recent version due to some fresh MBA grad reason like "be green, save energy by preventing people from pre-cooling their cars in the heat of the summer" or "this connected car feature is too unreliable and is making us look bad, so let's just remove it".
Porsche servers are down (I honestly would have expected an error message in the app, not just hide connection status and controls)
PS> Mine is back up too, as usual showing my windows are open when I start it. MyAudi is back up too. The interesting observation here is that they seem to be connected. I always figured they reuse some of the same software, but would have assumed run on different servers. Maybe not.
