You once said Firebase Remote Config made debugging harder in production. What created thatproblem?

A production debugging war story about Firebase Remote Config silently splitting users into different runtime behavior paths, causing two users on the same app version to experience completely different bugs. The root cause was not recording active config snapshots alongside crash reports, turning every incident into guesswork. The fix was attaching the exact remote config state to every error event and support log, making bugs reproducible again.
