Smart Alerts not working

My device got upgraded and set Smart Alerts as the default.  It failed to then alert me when I had a major leak.  My other sensor, nit yet updated, is sending alerts just fine.  The device was powered on and monitoring, because it showed my the thousands of gallons of I have lost, without giving a hoot.  Even an email would have been better than nothing.  I have since reset it to Manual Alerts, but would like to know if there is a bug in that new release?
