Unfortunately its not a joke. WD has, for what ever unknown reason to we end users, decided that the single bay v2.x My Cloud doesn’t need a shutdown option within the Dashboard like the older v4.x version has. Instead one is supposed to use WD Quick Access. One can search this subforum for “shutdown” to find numerous past discussions on this particular issue. There are a few unofficial alternatives from using SSH to using a web browser hack to unhide the shutdown option in the My Cloud Dashboard.
WD has a specific Knowledgebase article on how to shut down the single bay My Cloud units.
