Play Store Pre-launch: limited to devices that support ArCore even though "com.google.ar.core" is set to "optional"

Question

After adding ArCore support to app, and setting com.google.ar.core to optional in manifest file (as shown below), I'm seeing that Play Store Pre-Launch tests only seem to run on devices that support ArCore. Anyone else seeing this?

    <meta-data android:name="com.google.ar.core" android:value="optional" />

Answer 1

So, the issue turned out to be that I still had android.hardware.camera.ar set to required....when I updated as following then expected list of devices was now shown as supported.

 <uses-feature android:name="android.hardware.camera.ar" android:required="false"/>
