We just returned from Shanghai on Nov 8 and for travellers intending to use the luggage storage facility in PVG, please do note that the service is currently unavailable from Nov 4-11. We tried to store our luggage on Nov 7 but was informed that it was closed. There's a notice on the counter that says due to security requirements.
We were at T2 international arrival hall and was told no such service in PVG temporarily. Please have others back up plan in case you need to store your luggage.
