Viber notification doesn't disappear I use Viber on Android and when it is in the background, it shows a notification in the notification bar when I get a message.
However, sometimes when I click that message and it opens Viber, the notification stays there no matter that I'm actually reading it.

If I go to the message list, it shows unread messages, no matter I just read it. 
If I dismiss the message, it'll get back in a few minutes as it detects it is not yet read.

You can see here the notification is there and the message is already read:



What should I set to make it show the notifications properly?
This happened to me in my VIBER FOR DESKTOP (Windows).
(In my case the problem was caused by an unread CALL on viber; but I couldn't find it!!!)
This is how I located and solved the problem:
1.  I clicked on the conversations tab.
2.  Then clicked on the small triangle that appears in the corner
3.  I chose from the options:
    "Unread messages on top"
4.  Voila!!! The conversation came at the top, I clicked on it and the 'unread message' disappeared!
