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?
