I'm just beginning to look into versioning games in Unity and noticed that Unity seems to offer different things depending on the platform you are building for. For instance, Android and iOS seem to have their own individual properties for versioning while Desktop has no versioning functionality at all out of the box.
Since I'm working on a game that has builds for PC, Mac, Android, and iOS, I need to determine how we want to manage version numbers within our game without having to manually manage individual version for each platform. How do you solve this?
