 - Use proper SDK name for Session Replay tags ([#4428](https://github.com/getsentry/sentry-react-native/pull/4428))
 - Use `makeDsn` from `core` to extract the URL from DSN avoiding unimplemented `URL.protocol` errors ([#4395](https://github.com/getsentry/sentry-react-native/pull/4395))
+- Set `{{auto}}` if `user.ip_address` is `undefined` ([#4466](https://github.com/getsentry/sentry-react-native/pull/4466))
