Admin able to see the open tasks but the other users unable to find.

HI,

I have a task report to track the status of the task open and closed. Task entry is showing when task is with the context models. As the Admin user is able to see the tasks and close the task from task report by using complete processes smart service but the challenge is to the user can see that in actions Tab but he is unable to see the open tasks and to close that tasks. The task that entry is not visible for otherUsers. As a system administrator, I'm able to see it. I checked process security and user viewer access everything looks fine And I haven't used any filters in queryProcessAnalytics.

Any pointers will help.

Thanks in advance
