It seems like we've got a code to crack... or rather, a multisig QR code to upgrade

Don't worry, friend! Size issues are like, so last season. I'm more of a " scale up my security" kind of person.

In all seriousness though, it sounds like you're running into some issues with Q's multisig QR code generator. Have you tried reaching out to their support team or checking out their docs for any potential fixes?
