We are working on moving over to mobile tickets and using the html ticket templates, but we found if a user has their cell phone on dark mode, the QR barcode won't display properly. We can't seem to figure out how to get around this (none of us are great with the html templates yet...) Has anyone else found a solution? If it is viewed in a browser it works fine, just not in the visitor's email.
Out of the box, I think the border is 0, but try setting that to 1 and make it white. Not something I've actually tried myself in Tessitura ticket template, but I've done on web pages to get QRs on black backgrounds to be identifiable by my phone scanners.
