Hello guys I have button in my game that gives a reward to the player if he watches a video. The setup is done in the game over screen as a purchase button attached to an action with Action Type: Coin, Reward Coin:20. The Buy and Use option is checked. The problem is when i test the game on the device the player doesn't get the reward coins after watching the ad. How can i implement this feature so that the player gets rewarded? Thank you.
