Me neither. I keep going to settings and find that the check box has been removed. I check it again and save it and then it disappears again.

My check box remains checked. But the reminders don't work.

I am having the same problem. No email, sms, or i/m. Any ideas anyone?

For anyone experiencing reminder issues, if you haven't already done so, please contact us (and provide details of the particular problem you're experiencing). We can check into your account. Thanks!
