Why does my HTC One M8 Dotview Cover show a text notification when I have no texts?

[AC Question]

Ever since I updated to the new Lollipop version of Android, I seem to get false notifications on the dotview cover to say I have a text. It happens when I hit the button on the top left of the phone and the sms notification appears on the cover. A colleague of mine has the same phone and has started experiencing the same thing. We've both googled for solutions but no joy.... Any help appreciated!

I've been having a similar problem, although it didn't happen immediately when I did the Lollipop OTA update. My notification sound alert goes off about every 20 minutes even though there's no text, e-mail or other communication source that I've tethered to notification setting. Please post any feedback you get from HTC or other relevant source. Good luck.
