Try it before the session
Open a session on the Mac you will use for your class. Display the participant QR code, scan it with your phone and send a response.
If the connection gets stuck
Check that your Mac has an Internet connection. On your phone, try mobile data if Wi-Fi blocks access. If the app is reconnecting, give it a moment and try again.
Get back on track
If the issue continues, open Help → Connection diagnostics in the app. Tissyo support can help you find the next step. Describe where you are stuck without sharing passwords or participant information.
