I currently sync my Google Calendar to my iPhone via Exchange, and I usually have Google Calendar open on my computer at most hours of the day. If I set a reminder for myself, I get pinged on my mobile device, then a minute later on my browser.
I acknowledge the alert on my mobile, but that doesn't sync up in time to prevent the browser alert.
Any suggestions on how to avoid the duplicate alert? Or, can you suggest an alternative on calendar reminders in general?
