Currently, there’s no option to remove stale devices from Reporting.
Please introduce a “Device Cleanup” setting in the UI. This feature would be disabled by default, but customers could enable it to automatically clean up devices that haven’t checked in for more than X months.
The cleanup process could work similarly to Intune’s Device Cleanup rules, where devices are simply hidden from reports so they don’t skew the data..
totally agree, allow for an optional device cleanup rule like intune, so that if a device is more then x days then its deleted.
