The device doesn't have to be connected to have the app working. You can also select manually the device and type your current version.
Could you give me your current image version instead of OS version ?
It should be listed in Settings under "About".
Or if you know how to use ADB, could you give me the output of :
adb shell getprop ro.build.pandora.id
