Push Notifications sounds on older Android versions (9.0)

Please provide the following:

  1. SDK Version: 49
  2. Platforms(Android/iOS/web/all): Android
  3. Notifications


We built a mobile app for iOS and Android with Expo, and our backend web application successfully sends push notifications to both iOS devices (through APNS) and to Android devices through Expo’s push notifications service.

We use different sounds for different events on both iOS and Android, following the documentation and setting up channels for Android. This works without errors in Android 12, but the same app on an older Android 9.0 device only plays the default sound. According to the docs, there should be no difference since both are Android 8+ versions.

Any suggestion ?
