Hello @Fee
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues with bill reminders. I was taking a look and was able to notice that I can see upcoming dates in the Calendar so it's odd you're not able to here. I'm wondering what exactly is causing the issue. Are you putting the bills in the bills and income section or are you making them a future dated transaction? This could be a reason for the issue but it's difficult to say.
Once you have a chance let us know more and we'll see what we can do to fix the issue you're having.
Thanks,
Quicken Francisco
