AMA: Windows management with Intune

Is there any additional work being done on speeding up policy refresh on all device types? This is the single largest pain point for managing devices with Intune, there are times that policies and configurations take hours to update on devices. Also, offboarding users, we've seen many situations where a personal mobile device is registered and managed by Intune, but it will take up to an hour, and even longer, for data to be removed from the devices. I realize that much of this depends on Exchange and Sharepoint access tokens, but there are times, especially in a security incident, that we need to immediately remove data. Is there a way to ensure immediate data removal on personal devices?
