The callback for fbinstant.show_rewarded_video()
returns success true
and error nil
even if the ad has been interrupted by the player.
In a browser it works fine, and shows this in the console:
Game_wasm.js:1 FBInstant_PlatformShowRewardedVideoAsync - error: Reward not completed
Is this a bug, or is there another way of knowing whether the ad has been successfully viewed to the end?
