Good evening Adam,
First off, I would like to apologize for the delay answering.
We are currently experiencing a higher level of requests than usual.
Please rest assured that we are working hard at correcting this situation.
We appreciate your patience while we try to normalize things.
Thank you for sharing your findings with everybody.
This is really appreciated.
I am really glad you were able to get things working.
Is this because the sites’ web addresses are different?
Absolutely. QR codes will change when the URL does.
So yes, in short, if you have not changed the URLs on your live site, the QR codes will still work.
If you did, the only workaround I could think of is to use a redirection plugin so that the old URLs point to the new ones.
Let me know how that goes.
Best regards,
Geoff B.
