ShareGate Desktop crawls your connected SharePoint environments to get information on your sites and settings periodically.
This information is preserved in a local cache that the application can use to speed up your operations.
When you have this setting turned on in your report options, ShareGate Desktop will return results from the local cache instead of probing your environment.
Tip: Turn off Use local cache if you need to get the most up-to-date information in your report.
