May i request for your assistance regarding my issue on downloading apk file upon scanning the qr code from our prod environment using my mobile android device. I'll try the other environment DEV & UAT and i can successfully download the apk file. Kindly see the screen shot for your reference. Thank you

Hello Reuben,

Could you give more information?

Like, is the ssl certificates installed in production? Are you trying to install a debug or release mobile app? Do you have any different configuration in prod regarding firewalls, etc, that may be preventing you from download the apk?
