Aegixo sends notifications for Walk with me invites and subscription updates. Your own SOS does not need a notification: its progress shows live on the alert screen.
- Open your phone's Settings, then Aegixo, then Notifications, and turn them on.
- Check Do Not Disturb or Focus modes are not hiding them.
- Make sure you have an internet connection.
Everything is also saved in the bell on the Home screen, so you can read missed notifications even if the push never arrived.
