Defender ATP data transmission

Hi Community,

I have three questions:

1.  How frequently Windows Defender ATP data is sent by the endpoints to the cloud workspace?
2.  Is there a way to force endpoints to send Defender ATP data to the cloud workspace immediately?
3.  After an issue is remediate (e.g the version of Windows 10 is updated to the latest release) how much time is needed to see the change in the Security Center web console?

Thanks,

Luca
