Build Pipeline
Every store build for a release, from one button
Four storefronts means four signing setups, four backend answers and four version schemes. A script owning the counter is the whole fix.
Overview
Shipping one title to the App Store, Play, Steam and PlayStation by hand out of Build Settings is how a submission gets rejected for a version code that went backwards.
The window resolves the version once and derives each storefront's scheme from it, then builds every enabled target with the backend and architecture that platform needs.
