I've got a couple of QR codes that are returning 404 errors. The URLs are case sensitive. The QR link preview shows the url is in its case-specific format. But when I click on the link it returns a 404 error because the url has been converted to all lower-case after I click. I suspect this is a browser issue, rather than a QR issue. But has anyone else experienced this, and does anyone have a work-around? I'm opening the link in FF mobile.
