 Here is an example of the dialog box that appears when you click `Edit Devices` on the "demo2" menu. In this example, the device "362587269" is applied to the "demo2" strategy. The device "157333666" was originally applied to the default strategy but will be applied to the "demo2" strategy after clicking `Save`. The device "232026634" has a device strategy for "demo1" and a user strategy for "demo2", since the device strategy takes priority, this device will be applied to the "demo1" strategy.
