Since I’ve started using Unity Ads, some games are in a organization called "Missing name - Unity Ads (NUMBER)" (the oldest ones) and the new ones are using another organization.
Don’t know how it happened but now I have all the games split into these two organizations.
There is a way to transfer all of the projects over to a single organization and to consolidate revenue.
If you are an Owner of both organizations, you can go to Unity ID and select the project you want to transfer. Then click on the Settings tab, select a new organization to transfer the project to, and click the Transfer button.
To transfer over revenue, please contact support at unityads-support@unity3d.com. Please include the organization that contains the revenue, the organization you want to transfer the money to, and the amount.
