Activity is showing all other people's activity and tasks

Currently, i have 30 users and we are adding tasks and activities round the clock.
The problem is that any user is able to see all other users’ activities, click on their tasks and see them.

Irrespective of the task’s status whether private or not.

Is this a bug, or a setup i missed?

Hello,

Task visibility is not related to Activity screen. A task can be seen by team members if it is shared with them.

  • It is possible that you place tasks in a project that is shared with Everyone and everyone is able to see those tasks.
  • Other possibility if you have task Sharing defaults set to share with everyone. Check the Settings - Task preferences.

Hope this helps.
