At least in my experience I have more customization issues when taking to people rather than using an app or going through a kiosk. The only time it's the other way around is when they don't include an option I want on the digital version but that's becoming less and less common for me at least. The number of times I've had orders just missing customization things I asked for but they didn't hear or forgot to enter is much higher when I go through the drive through or go in person then when I do it through something digital.
