Reward Coins Doesn't Increment On Phone But Works On Emulator

I am using Buildbox 3.2.1 and deploying on Android.

I have added a reward video and once ad video is completed I am adding a coin. Player can click on reward video multiple times and number of coins should increament every time. All good it works on emulator, but when I test is on phone onle one coin is added even if I click multiple time. Actually coins are not incrementing when reward video is completed multiple times. This issue is only after deploying on android phone.

I tested this on multiple android version and behavious is same. Would appreciate if any quick solution or workaround

URGENT: Any inputs or help on the mentioned issues of not incrementing the coins after reward video.

I AM STUCK WITH THIS ISSUE TO RELEASE MY GAME. Appreciate any inputs.

 

Solved adding a different delays for adding coins and for menu jump. Thanks to support team (Hue) for quick response.
