I had the same problem.
Removing the family link supervision waiting a few and refreshing worked for me.

I purchased a M365 Family subscription so I could use Defender for Individuals on my and my children's devices. The subscription is being shared with both children's MS accounts. I can sign into Defender normally on my PC and Android device, but when I try to sign into the Defender app with their Microsoft accounts on their Android tablets, I get an error: "Invalid license, please contact administrator".
This is happening on two different Android tablets with both their accounts, so I don't think it's a device based issue. Is anyone else seeing a similar issue trying to setup Defender for Individuals on a M365 Family subscription?

Same issue here. What is Microsoft doing about this?
Can you try logging in using your own Microsoft account on their devices to see if you can log in successfully?
Actually, even if you don't have an existing Microsoft 365 Personal or Family subscription, you should still be able to log in successfully using an Outlook email address without any error. It's just that once you logged in, you will be seeing a prompt message asking to get a Microsoft 365 subscription either PERSONAL or FAMILY to be able to use Microsoft Defender.
Here is the actual screenshot of the prompt message when logged in to the Microsoft Defender app for Android using an Outlook email without a Microsoft 365 subscription.
Yes, both are @outlook.com email addresses.
Are your child's email addresses both an Outlook email?
