We only see SMS the Android SMS stack exposes to the Device Monitor module. RCS ("Advanced messaging", chat features in Google Messages) often never shows up. Group MMS is similarly patchy.
- Confirm Device Monitor is still installed.
- On the child's phone, Messages → settings → turn RCS / Advanced messaging Off (Google Messages: Settings → RCS chats → Off).
- If there is no RCS toggle, try VoLTE Off, reboot, send a test SMS in and out.
- Check the Parent app Calls & SMS or Web Center Communication.
In-app messengers are not SMS. Use Screen Mirror or AI Shield for those.
We cannot block texts. Call and text visibility.
