Hello cmbglw,
Welcome to Apple Support Communities!
We understand from your question that you are not getting a QR code through email. We can certainly help you with this!
Are you using the native mail app to view your emails? If so we would try using a browser to check your email to see if the QR code is visible.
We would also make sure the QR code is attached in the email. We have had many a time where the attachment was forgotten.
We hope this is able to resolve your issue. If you have any more questions or this does not resolve your issue, please reach back out on the thread!
Cheers.
