Check notification permissions in the app

1. Open Carbinox Pro → Device → Notification and Reminder → App Notification, and make sure the specific app you're missing notifications from (e.g. WhatsApp) has its own toggle turned on — the "All App Notifications" master switch being on doesn't automatically turn on every individual app.
2. Also confirm the phone's own notification and location permissions are granted to Carbinox Pro in the phone's system settings.
3. On iPhone: Settings → Bluetooth → the (i) next to the watch, and make sure "Show Message Notifications" and "Share System Notifications" are both on, and that Settings → Carbinox Pro → Background App Refresh is on.
