I was going through the ChurpChurp app over the weekend and these two campaigns appeared on it.
UAT stands for User Acceptance Test and probably the two was targeted at the advertisers to see how their campaign would like on the app.
It shouldn't have appeared on the end-user app but it did.
I wonder if other Churpers saw these two campaigns on their app recently.
