We have a form that was developed by one of my teammates. The QR code box turns grey once the user types in the Date field (or any fields connected to the collection related to the QR code). The problem is that this issue does not occur for a couple of us but it does for others. So I'm trying to figure out what the difference is between us. If anyone has any ideas please let me know. I have included a screenshot below of what it looks like and have uploaded the files if anyone want to take a stab at it.
the PDF works fine here with Acrobat Professional. I assume you have Acrobat Pro as well?
Do your teammates use Adobe Reader when it does not work? In that case the PDF is missing so called Reader Extensions. You can extend the PDF with Acrobat but not for the barcode option as far as I know. You need to have AEM Forms server for that.
