After enabling the required permissons (Notification, Location, and Accessibility Service), you will become eligible to earn Points automatically.
Keeping the RewardBox app live in your device background with the permissions on, inside the app you will start generating Points. 1 Point will be generated every 60 minutes. And you have to claim it manually to your in-app wallet.
You can collect up to 24 Points maximum at a time, meaning that if you do not claim the 24 Points into your wallet, the app cannot generate the 25th Point. Please remember to claim it before the vault is full!
