I am an admin, I have some tickets assigned to me but I look at global tickets more than just mine. I personally do not like tickets assigned to me, because no one else can see them. I tend to leave tickets in the queue, unassigned so they are more visible. Thats just how I use it, thats not a request to change anything.
If I go to the top, then select All Active, it still only see mine. The My Active and the All Active show the same tickets when All Active should show a lot more.
I tried doing Custom: All Dept, All Group All Agents, Status : Active... still only go My Active.
using the web app, I can see all the tickets.
