Thank you! This feature is definitely missing.

+1 ... this is a deal-breaker feature to receive updates on config changes.

Is there any timeframe when this feature might be added to plugin as part of 5.3.0 !?

The Realtime API is quite new. You still receive updates on config changes but not yet in realtime. There is no ETA yet. PRs are welcome (please let me know beforehand). You can also prioritize this issue as sponsor.

The task is to add support for realtime config updates to the Firebase Remote Config plugin. The base branch to be used is feat/issue-499. This branch already contains the necessary type definitions (see #502). The implementation should be the same as the addDocumentSnapshotListener method of the Firebase Cloud Firestore plugin.

This is now available as dev version:

npm i @capacitor-firebase/remote-config@5.3.0-dev.8e93695.1702565523
