I'm new to Doit - been trialling it for a few days.

I was using Doit.im HD, version 3.9.16, and I've been having issues with the 'Overdue' task badge. When a task is overdue, the badge does not automatically update, like it does on the Apple Reminders app. Instead I have to open Doit before the badge updates. I downloaded 3.9.20 yesterday but the issue remains.

Is this normal? I hope not, as I would expect the badge to be a basic feature and its frustrating having to open Doit to check if I've missed anything.
