Ads not showing in published app (Android)

[krrskl]

Hello!
Anyone have a app published in the play store using Meta audience network to monetize these app? I have one but all the apps with anywhere user return No fill. I created a minimal app with the same domain package using Kotlin and published as internal test app and the same apps works fine.

My Flutter app, when is published in the Play Store the ads not are displayed, but in release or debug mode using testIds work fine.

Error captured using flutter logs, running the app downloaded from Google Play Store

"error_message": "No fill",
"error_code": 1001,
"invalidated": true,
"placement_id": "10198386XXXXXX_10198482262XXXXX"
}
