I have the same problem. It takes forever for my TP to notify me of new emails and it also takes just as long for it to remove the notification of a new email when I read it from another device or my PC.
One time it took 6 hours for it to remove an email notification.
I am going to. I have a huge list of bugs/problems that I just haven't had time to enter into the Bug thread. Not to mention I have to read the whole thread first to make sure I'm not submitting a duplicate bug that's been logged into HP's ticket system.
