Sometimes our devices don't report location for extended periods of time, often because the user disabled location tracking for the SimpleMDM app. Typically we learn of this only when we go into device details for an individual device and notice that the map says "updated about 2 months ago," or something similar. It would be nice if there was (a) an email notification to administrators if a device has been turned on and checking in with MDM, but hasn't reported its location in x days, and/or (b) a way to report all devices that, again, are on and talking to MDM, but have not reported their location in x number of days. This would allow us to proactively work with the users to get location tracking working again.
