Why does my LinkedIn inbox always show one unread message ?

Even if I have read all of my Linkedin messages , it still shows one unread message. Strange but true.
I am not sure what is the problem but i can tell how i fixed that.

  1. Click on any message that you have already read.
  2. Mark it as UNREAD
  3. Click on another message that you have already read.
  4. Mark it as UNREAD

See , if you notice any change in unread messages indicator ?

For me it changed correctly and then I read both messages one by one and it made my all messages as Read.

Have great time using Linkedin :)
