Microsoft Account not showing Windows 10 Licence


I had a notebook with local users and a copy of Windows 10 Pro activated. So I decided change the local user into a Microsoft Account to link my license with my MSA.
On the device it's allright, now teh activitaion tab shows "Windows is activated with a digital license linked to your Microsoft account". But my MSA doesn't list this device in devices list. I have other devices activated that are listed, but not this one.
Anyone know what's happening? Why my device is not listed in MSA?
