I am using FCM messages on my android project. I have read this info on developer page;
High priority messages on Android are meant for time sensitive, user visible content, and should result in user-facing notifications. If FCM detects a pattern in which messages do not result in user-facing notifications, your messages may be deprioritized to normal priority.
I just want know , must we show user-facing notifications even if app is on foreground? if we do not show notification when app is on foreground (any activity is visible) May it cause any deprioritization?
