Hi, i've started using Chartboost in one of my apps and one the first day the revenue per install was almost $2 which seems quite high. Since then it has dropped to a small fraction of this. On the second day I received 47 click, 1 install and $0.27 revenue. The next day I received 20 clicks, 1 install and $0.04 revenue. I really don't understand how the revenue per install has dropped so much. Has anyone else experienced this?
