I received an email over two hours ago saying "We Are Preparing Your Cisco DevNet Sandbox Lab." (Meraki Small Business.) The "Setup" button in the workspace started blinking, and soon it changed to "Setup will finish in less than a minute." Two hours later, it's still blinking saying "Setup will end shortly." (Also in this form, the Labels box at the right is always pre-filled with the text "DevNet Sandbox," which is an illegal value for the Labels field and raises an error.)
