Yes, the user guide needs an update. Nevertheless, your screen save of the Wi-Fi setting in the dashboard shows your MPW is connected to the network Shangri-La. Once your MPW is connected to a network, you (and others) need to connect your devices to that network, and not the direct connect to MyPassport wifi signal anymore.
Here is a screen save of my MPW connected to my home network: Notice that my screen shows no connected devices (because my MPW is on the home network wi-fi, and so is my PC), whereas you appear to still be on the MyPassport signal. By being connected to my home network signal, now I, and anyone else with access to my home network wi-fi can connect to the MPW. So fix that ,and all should be OK. Just connect your PC and mobile devices to Sharangri-La and open My Cloud app. You also can get on the dashboard this way, too, by using Safari browser on an iPad… If you are using Android, then use an Android browser.
