QR code not working

Hello Cybermadhatter,

Thank you for using Apple Support Communities. Sounds like you can't AirPlay. If so, we would like to help by sharing a helpful resource that has steps you can try to sort this issue out. Click here: If screen mirroring or streaming isn't working on your AirPlay-compatible device - Apple Support

Try these steps first

After each step, see if you still need help. 

1. Make sure that your AirPlay-compatible devices are turned on and near each other.

2. Check that the devices are updated to the latest software and are on the same Wi-Fi network. 

3. Restart the devices that you want to use with AirPlay or screen mirroring.

If you're prompted to enter a password, you might have restrictions turned on, or you might need to adjust your AirPlay password settings.

We hope this helps out. Thank you for using Apple Support Communities. Take care.
