I originally had a Daily PO for killing bugs, I refreshed it and got a Daily PO for unranked warzones. I then completed two warzones (confirmed by seeing in the conquest menu, having the box ticked in "Daily priority missions" on the GS tab of rewards and tracking progress in the Weekly PO I have for unranked warzones) but I have not been granted any GS points, I'm still 0/800.
