Although the probability of such a scenario is not too high, we do have a built in solution for that, which is to share the revenue equally between apps.
For each device in which there is more than one opted-in active users on the same day, the count will be split between the apps.
Example 1: 2 different partners have their apps with Bright SDK running on the same active device. Each active day will count as 0.5 day for each partner.
Example 2: The same partner has 2 apps with Bright SDK running on the same active device. Each active day will count as 1 day, for all the active apps altogether.
