+- If native crashes do not appear in Expo, verify the app is not running in Expo Go, rebuild the native app after installing the package, and check that `ios/Podfile.lock` includes `exceptionless-react-native` (autolinking).
 - If simulator submissions cannot reach a local Exceptionless server, use `http://localhost:<port>` for iOS Simulator and make sure Metro is not running in Expo's default LAN mode. Physical devices need a reachable LAN host.
 - For malformed or unexpected stacks, verify behavior in `ReactNativeErrorPlugin` tests before changing parser logic.
 - For native crash report loss concerns, verify `NativeCrashPlugin` only clears pending reports after at least one report is retrieved and submitted.
