I've managed to unpause the devices via the VM connect app but to do so I have to start the app, click unpause the device, wait for a minute or so for the flywheel to spin a bit, close the app, reopen the app, click unpause again, the app then reports an error, refresh the app again and voilà, it's unpaused the device. Whether one can describe the app as 'working' using the described method, I'm not sure.
