Hi @Marie Becker,
I understand you're wondering if prototype links remain active even after updates are made.
I tested this on my end using this QR Code Generator and a prototype link : if you copy the prototype link from the share modal and then update the prototype, the link will continue to work and display the latest version of the prototype.
However, I found that if I remove a prototype frame, the link no longer works properly. This suggests that major structural changes might affect the link's functionality.
Additionally, if you update the sharing permissions, the link could become inaccessible to certain users depending on those changes. You can find more details here: Share files and prototypes
Given these points, we recommend testing your prototype link before generating a QR code to ensure it behaves as expected.
Thanks,
