# Participant Auto Join Issues

If participants are having trouble automatically joining the presentation session, there are a few things to consider:

1. **Bonjour Protocol**: First, make sure your Wi-Fi network supports the Bonjour protocol.
2. **Network Connection**: Confirm both the Organizer and Participant devices are on the same Wi-Fi network.
3. **Latest Version**: Make sure all devices are running the most recent version of the Presentation Room app.
4. **QR Code as Plan B**: If the automatic join feature is not working, the Organizer can display a QR code. Participants can scan this code to quickly join the session. To display the QR code, go to the current group action menu and select **Show QR Code**. Participants can then scan this using the Scan QR Code option in their app.
