Yes, I tried several times with or without factory reset. In my experience, factory reset is waste of time. I have to set up everything all over again but it never helped. If the firmware is supposed to work, it works by installing the same firmware about 3 times with multiple reboot.
Now, I realized that I am not even getting the text notification by email. This is definitely the firmware issue and I know for sure because recent 5029L firmware has the same problems. No email notification and no percentage setting for motion detection. Dlink asked me to go through multiple steps but they gave up. I notified D-link regarding this issue but they are in denial and still asks customers to go through unnecessary steps.
