Unapproved Reports On Application Start
Controls whether unapproved reports are deleted on application start or not.
Silent and Toast reports are automatically approved. Dialog and Notification reports require explicit approval by the user before they are sent.
On application restart the user is prompted with approval for one unsent report. So you generally don't want to accumulate unapproved reports, otherwise you will prompt them multiple times.
If this is set to true then all unapproved reports bar one will be deleted on application start. The last report is always retained because that is the report that probably just happened.
