i'm building a flutter App which i am monetizing through Ad mob. i'm specifically using the banner Ads for now.

but here is my issue. in my simulator, i can see the test banners in Android 9 and Android 11 i can even see them in a real Xiaomi Android 9. but on a Galaxy S10 i can't see them.

i already tried to add the permission

<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

have you ever experienced a discrepancy like this ? how can i debug in a real device?

EDIT:

so i connected to the device by pairing it via Wi-Fi and i got

UseRequestConfiguration.Builder().setTestDeviceIds(Arrays.asList("0E9819CC3AEA7F45DCB97C80DCE78CF6")) to get test ads on this device.

thank you for your help !
