Switching environments

In the panel header there is environment switcher: Sandbox or Production (tooltip: "Switch to Sandbox" / "Go to Production"). Click - browser opens the app in the other environment on the same "page" (e.g. offer list stays offer list). On Sandbox the UI may show Sandbox label.

Maintenance page

When the platform is in maintenance, instead of the panel you see maintenance page with a message. Often Go to Sandbox is available so you can continue in the test environment.
