do you mean the element „scan code“ within your bound or the starting QR code?
If you mean the starting QR code, you player can also start their bound with the bound url (above the starting QR code in your creator mode). If you mean the element „scan code“ unfortunately no. If the QR code doesn’t work (for whatever reason) it doesn’t work. But you can first use your own codes or activate the option, that they can continue playing the game without scanning the code (with skipping the element).
I hope this helps you for the moment.
