Maybe this is little unusual question, but I don't know where else to ask. I am using calendar app in windows 10, as a default calendar app on my desktop. when I put some reminder it does appear on windows, but NOT on my iPhone. I am using google calendar and google account for calendar, both on windows calendar and my iPhone. It happens also otherwise. If I put a reminder on my iPhone, it doesn't appear in calendar app on windows. So only reminder is a problem. Events appears both on windows and iPhone, and are synced ok. I guess it's a problem with windows calendar app, but don't know how to solve this. It causes me lots of unpleasant surprises. i missed few of my appointments, because reminder, which I set, didn't show on my iPhone.
