What's the difference between Standard Geofences and Community Geofences?

Both Standard and Community Geofences can be used to send broadcast messages and check-in requests. The key difference is that when users enter the boundaries of a Community Geofence (colored green on the events map), they will be automatically prompted to join that particular community within your organization. Standard Geofences (shaded blue on the events map), on the other hand, do not automatically prompt app users to join a particular community. Please note, Community Geofences are specific to organizations using the Enterprise Structures feature.
