Stick Up Cam not detecting motion at all

I recently installed a Stick Up Cam. Initially it worked fine but now it does not pick up motion at all. I checked all motion setting, zones, notification settings on my phone, nothing helped. Reinstalled the cam several times and reset to factory settings. Nothing brings back motion detection. Live View works fine. This is very annoying as this is a brand new device I purchased 2 weeks ago. I wonder if someone could help. Thanks.
