the problem used to be very visible in early app development: you get android apps that try to imitate ios. the navigation is wrong, the inputs are wrong, the ui language is inconsistent.

it happened all the time when almost all of the graphic designers (which were thrust into the roles of UI designers) were on mac and usually ios but got the task of "designing an app", which meant _one_ design for both ios and android. as an android developer i had to fight the OS, the framework and pretty much everything else to make the designers vision work, which resulted in buggy apps that felt unintuitive to use.
