Missed notifications directly hurt response time. Desktop, mobile and email alerts each have their own failure modes, so check them separately.
Mobile push
Check system notification permission, battery optimization and background execution; Chinese Android builds also need vendor channel setup.
- Enable system notifications
- Disable battery restrictions
- Verify vendor push channel
Desktop alerts
Confirm the client is not muted and quiet hours are off, then send a test message.
- Check OS notification settings
- Confirm quiet hours are off
- Send a test message
FAQ
Only some people miss pushes?
Device-level permission differences — have them check notification and battery settings.
Pushes arrive late?
