Hi,
We have log flushing for Mobile Device Inventory Reports set for one week because of our larger then usual on-prem environment (~65k mobile devices) and recently noticed several of our devices reporting their last inventory date as 1970-01-01. Looking at the reports db table we can't find the devices in question anymore. This is resolved when the devices are checked-in again but during the short time that they don't have a last check-in record they start de-scoping apps and profiles.
Does anyone have any idea of what could possibly be causing this?
