Maybe it just needs to be turned on by the manufacturer. They probably use the same motherboard for all their models and turn on or off features depending the model and price.
These mini-PCs are mostly made by a couple of large manufacturers in China then Distributors put their names on them and supposedly provide support. I have tried getting ahold of the customer service department for this device also located in China. They are nearly impossible to get any action from. I just have to decide if it is a good enough value to keep or send it back because the advertised features do not work properly.
