Block Only YouTube not Google Applications

[Christian_Garci]

Hi Mates,
One question please, we need block only YouTube in App Control and Url Filtering. 
When we try to do that via YouTube App of CheckPoint, the Block dont work becouse Google Service is allow.
When we block Google Service, these Block Gmail and other Google Applications.
The last rule is Allow All and we are not using HTTPs Inspection.

MGMT is 80.10 and Firewall are 77.30.

Do you have any idea how to get to this solution ?

Thanks
