I got the email from Google as follows: -
Hello Google Play Developer,
We recently announced that we’ll be deprecating the install_referre
com.google.firebase:firebase-core and com.google.firebase:firebase-analytics using this broadcast intent internally. You can check it by merged manifest in android manifest file. This receiver is using install-referrer intent.
com.google.android.gms.measurement.AppMeasurementInstallReferrerReceiver
Either We can directly remove this explicitly by adding below line in android manifest.xml file but it will lead to disrupt the install referrer mechanism in case if your app is using conversion tracking or any other install campaign or we should wait for the next update of firebase libraries.
