I have set several cards with Due Dates and Times, but the notification panel (bell) has nothing in it. Several notifications have already past, and I have not seen any notifications in the panel or received any emails.
I looked at the Trello help for this subject, and the link there to send a test email successfully sent me a notification email. So that is working, but Trello is not doing its job.
My profile notifications are set to Instantly. So, it should be sending emails.
Thanks,
Richard..
