On an existing permit when the insurance expires it would be great as a district admin user to receive an email that the insurance is expiring and that the permit still has approved dates on it.
There is an additional notification setting that allows you to adjust the timeframe of when you would like to be notified that the insurance is expiring. The default for this feature is 30 days. You can find this setting in Settings->General Settings->"Days Notice for Expiring Insurance".
You won't be notified about changes to this idea.
