You're right, non-immigrant visa serves are suspended yet consulates still allow you to currently schedule appointments (at least this is true for Germany and the UK). I assume once you get closer to your scheduled appointment, it'll automatically be cancelled for as long as consulates remain closed. In terms of the expedited appointment, I was told (again, this applies to Germany) that as long as the US travel ban exists, all requests would automatically be denied, so I'll need to wait until the ban is lifted to have any chance at getting the emergency request approved. Sounds like you're in a similar situation - I hope things work out in the end!
