Note

Low Risk
Version-pin-only dependency bump with no wrapper code changes; validate messaging/inbox behavior on real devices after upgrading native deps.

Overview
Bumps the pinned Customer.io native SDK versions used by the React Native wrapper, with no changes to the JS/TS public API in this diff.

Android customerio.reactnative.cioSDKVersionAndroid moves from 4.18.2 to 4.20.0 in android/gradle.properties. iOS cioNativeiOSSdkVersion moves from 4.5.3 to 4.7.0 in package.json (Pod resolution follows that pin).

Consumers get upstream fixes and features (e.g. iOS 4.7.0’s Visual Notification Inbox overlay) after a normal native dependency refresh (pod install / Gradle sync).
