Can't link admob with firebase iOS/Android project

Question

I have two accounts: \"A\" and \"B\": A is main account that hosts iOS/Android unity mobile game on Firebase. B is using for admob integrated to iOS/Android mobile game.

Looks like you have to use the same email address that created the Firebase project. Despite what the documentation says, you can't just grant "Owner" to another account. I had the same problem; creating a new Firebase project using the same address in AdMob allowed me to link the two.

In case it's useful, here's the forum I found: https://support.google.com/admob/thread/12976824?hl=en

In this case the pub can reach out to the Firebase support - https://firebase.google.com/support?category=troubleshooting&hl=en This may also happen due to the complexity of Firebase. Firebase can only be linked with the first email id that was used to create it. For example if the company has 2 employees and Firebase was created using the id of Emp1 then Emp2 cannot use his email id or company email id to relink Firebase (in the absence of Emp1).
