Campaign Stats Clarification

Hi, I don’t get some campaign stats numbers, if someone could explain me this, I would really appreciate it.

As an example in my latest push campaign there was:

  • Successfully sent and delivered 5900 notifications
  • Out of which 122 were clicked and 462 notifications closed (excluding Mac users)
  • I have 118 MacOS users

If we calculate the numbers 5900 - 122 - 462 - 118 = 5198 of notifications that were neither closed nor opened. So my questions is what happens to the rest 5198 notifications?
