New UBook X doesn't have valid Windows 10 Key?

I ordered and received yesterday a brand new UBook X from Amazon (Prime Day special) however I got it all set up and today it’s complaining “We can’t activate Windows on this device because you don’t have a valid digital license or product key” I tried going through the troubleshooting but it still says the save thing, doesn’t this product come with an OEM key?

I have the same issue and i already contacted the service center and so far no reply! If you get any joy please send me a message and i will do the same!
