I just noticed something...
So I still use my old zmax for apps/games (wifi only) and it's apparently signed into the same google account as my new zmax pro. If I setup a calendar event on my old zmax, the even notification will go off on both the zmax and zmax pro. I guess because it's synching with my google account. But yet calendar events set on the zmax pro directly do not work. I also noticed in the Calendar settings it lets you switch between MyCalendar and calendar that's assigned to my google account. Switching from MyCalendar to my google account's calendar on my zmax pro makes no difference. The events notifications still do not work.
Very confused!
