my company is issuing documents that have QR codes (for verification. to try and counter counterfeiting). scanning them leads the user to the original file issued by our company. I use firefox as the only browser on my android device. when i scan QR, the link returns a .bin file instead of .pdf And from past 2 months i have been asking our web developer to fix the issue. Poor guy has verified multiple times and returned with the same answer that it works fine for him. god knows how much time he wasted in troubleshooting this wicked bug. Just a few minutes back i used a device with a different browser and it worked perfect. i then installed edge browser on my device and voila, it works perfect. how can this be possible? heres the url after scanning the QR code. http://healerkart.com/api/219405270ac5e3e4fb8f355f421ffcbc fyi i am facing this issue on the android version and not the windows one.
