Android App Notification Sound is disabled/off by default


We are trying to get sound for the notifications we send to our expo app. We have specified the sound as “default” but still no luck.

What we have observed in

“Settings” -> “Notifications & Status Bar” -> “App Notifications” -> “Expo”

Sound is disabled by default. We think it’s the default setting for all the android apps depending on user settings but some how WhatsApp Sound Settings were enabled after installing the app.

How to enable these settings by default when we install the app ? We will finally distribute our app by ejecting or build standalone. Is there any way we can enable these settings by default ?
