When I did the update from notifications, the admin console did shut down, then some time later opened up again and opened all our file. However, it didn't start the WPE. In earlier versions there was a button that showed whether the WPE was on or off, and turning it on was just a click. Now you have to go to AWS, find the EC2 instance, and reboot the instance.
I think after an update, the WPE should be automatically restarted.
Also, please restore the button showing the status of the WPE. This should be an integral part of the admin console.
