I have a task that is due at 7.00 in the morning, I have not set a reminder for the task.
I get an email notification prior to the time.
I get a notification on my Android phone prior to the time.

If I clear the task on the web app, this gets pushed to the phone and the task is cleared, but the notification is not cleared.
I have to manually clear the notification on the phone.

Is this correct, or should the notification be cleared when the task is cleared?
