Trying to Push GPO Through Azure ADDS

Hi,

I'm new to the whole Azure Domain situation and I've managed to self teach myself through deploying a new domain.

I have a 2016 Data-centre VM running joint to the AD DS, all the users on Azure AD are showing on the AD built into the server, however when i try and push a GPO out applied to a specific user/group, it is not being picked up on a PC that is Azure joined (shows up in devices in Azure AD) and logged in by one of the users the GPO should be applied to.

Am I missing something obvious here? Let me know if more information is needed.

Kind Regards,

TeeKay
