Energy is a separate in-app resource. It is not FFC and it cannot itself be withdrawn.
Where the app offers an optional rewarded ad, the screen should clearly state the in-app reward before the user chooses to watch. Reward delivery is tied to the rewarded-ad completion/verification flow.
Energy ad watches can have daily limits and cooldowns. The account-specific counter shown in the app is more authoritative than static website examples.
Separating Energy from FFC makes it easier for users to understand which resource is an ad-earned utility resource and which is the app’s virtual FFC reward balance.
If an ad closes without a verified reward, do not repeatedly tap or force-close the app. Refresh the Energy status and use the in-app support flow if the server still shows no reward.
