Will pinned tomato form editing and then changing it affect the previous QR code?
No. Changing a Pinned Tomato form after editing it will not affect the use of the previous QR code. Every time you edit a form, Nail will generate a new link and QR code for the form, and the old link and QR code will still be valid. Therefore, you can make form edits and changes with confidence without worrying that the QR code that has been generated will not work.
