Unable to sign-in to Microsoft Defender on Android devices for child accounts

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?

    Maybe you should try disabling first the Google Family Link temporarily then log in on the Microsoft Defender app on your child's devices then once successfully logged in on the Defender app then re-enable the again the Google Family Link.

    If my suggestion above didn't work, I would suggest contacting the developer of the Defender app on the Google Playstore by searching Microsoft Defender from the Playstore and then clicking DEVELOPER CONTACT's email address atpandr@microsoft.com or leave feedback by rating the app.

    Thanks Emmanuel. I attempted to sign-in on their devices using my own account and got the same error ("Invalid license, please contact administrator"). I've signed in using my account on my Android phone and did not have this problem, so that account is working for login on another Android device. It looks like the problem is on those devices, but they are two separate models of Android tablet (one is a Samsung Galaxy Tab 8, the other is a Lenovo Tab M8).

    I was looking through reviews for the MS Defender app on Google Play and noticed someone mentioning they were having the same issue as me. They blamed the issue on Android devices that are being managed via Google Family Link (for parental controls). Are there currently any known compatibility issues between MS Defender for Android and Google Family Link? My children's tablets (where I cannot sign in) are managed by Family Link, whereas my phone (where I signed into Defender with no problem) is not. Is that possibly a bug that we can raise to the Microsoft engineers working on Defender? Thanks for all your help.

    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.
