I am making an app with the push notifications component.
Generate push notifications from a VPS with php and MySql through the Onesignal API, I need it to have custom sound, but it does not work, when the phone receives the notification, it does it with the default sound of Android.
The tests I do on a Samsung J7 with Oreo 8.1
I created the Android categories in Onesignal, and send the messages following the API recommendations, but the custom sound does not work.
Has anyone had the same problem?
