Something is happening with InMobi. I do not think that they should take so long to approve an advertisement.
For example, my first campaign in Inmobi was approved two days ago. The first day I received 200+ impressions and only 1 click on one of my 3 ads. After that, yesterday (Saturday) I received no impression on all day, and so far today I have not impressions.
Yesterday I also decided to raise the CPC to 0.06, but I get nothing. It seems very strange.
By the way, my campaign targets traffic from Spain.
