Problem with Chartboost reward video
I have a store in my game where the player can buy stuff with the coins. If they don't have enough coins, but still tap an item, a message pops up offering them to watch a video for 100 coins.
My problem is that I have a ton of items, but when I do an ad hoc test, the reward video either shows up once or never. I tap an item, message pops up, tap the watch video button, and instead of a video popping up, the watch video message just disappears, and it also does not add any coins.
Is Chartboost set to just show one video when testing?
I also read somewhere that sometimes Chartboost doesn't have enough videos to show and just leaves the ad space empty.
