I have an update on the second shift for Model Y production at Giga Shanghai. It looks like it was temporary and they returned to a single shift after a short time.

Eventually, production should be 23K/month with 4 shifts but there is only a single shift right now (5750/month). https://t.co/inYnbPIZnj
