We have a ZMD-DX-SIN8 and have not gotten cell phone notifications for a week. We get the motion detection events if we check the phones but no notification of the event.
We rebooted the DVR, the router, and our phones. I have turned notifications off and on a few times as the Meshare help suggested.
We would sure like to be notified if someone is coming to do us harm. There is no buzzer or alarm on the "security system," so without notifications there is no security.
This keeps happening until I complain and you get your servers working correctly.
