Ours is showing the graph and cost, but all keywords show zero for everything, so no idea what is actually going on. One campaign in product listings has been active for 3 days with so far zero cost - so not sure what the status is.
I found it interesting the last few days. We let our paid click bank run out and did not feed it more money. Normally we would still get quite a bit of the free clicks even with out spending any, but now it seems they have turned the dial down on the freebies.
