I'm working on a Jetpack Compose app that uses Google Sign-In via Firebase. The strange thing is, the app logs in correctly when built and run on one computer, but when I build it on a different machine (even though the code is identical), the Google Sign-In fails.

What I've Checked So Far:

SHA‑1 Fingerprint: Verified that the SHA‑1 is correct and consistent on both machines.

google‑services.json: I have the file in my project.

a bunch of other things but i don't remember now
