Every native app I've used works everywhere I've used it, every time as well.
That native apps were wildly unstable, or that it was impossible to find native apps that ran on different platforms before Electron is a myth. Electron didn't solve those problems, because they weren't problems.
Electron solved the problem of "how can I, a web developer, run a website on the desktop but make it seem like a native app and call myself an application developer?"
