I have been using the stand alone version of the notifier. I have noticed lately that I am getting a large number of false positives. My sound and light blink like I have a new message only for me to go check and find out that no one loves me. It is quite a slap to my delicate ego As far as no new notifications, I have yet to see this. It has happened to me in the past when I clean up some old messages, but after I receive 1 or 2 new ones, it worked as expected.
