Summary
Certain users on our team see all other team members as being logged out.
Steps to reproduce
We have about 20 people at our company and only 2 of them have this problem. One is using Windows 10 and the other is using Windows 7. When a user who's account works on another computer logs in using one of these two computers, the same problem occurs which indicates it is a setting on the computer or perhaps some network config issue. When users log in from different network locations/configurations, the issue doesn't change, so it's likely a computer setting rather than a network issue.
Expected behavior
Users on the left-hand "Direct Messages" section and the channel dropdown should indicate with color and icon that they are logged in/connected.
Observed behavior
Users under "Direct Messages" on left hand menu appear as grey with an "x" even though they are logged in/connected to the system and other users on the same team who are working properly can see them logged in. The channel drop-down for users at the top also displays users as being logged out.
