Hello, @fresh-football-47124 and @brief-honey-45610. I attended the office hours and mentioned the Multiple exposure warning in our experiments. This is an experiment we are running. We have a NextJS application and are using client components for it. Our code looks like this in _app.js:

setPolyfills({
  SubtleCrypto: crypto.subtle,
});

export const growthbookClient = new GrowthBook({
  apiHost: "<https://cdn.growthbook.io>",
  clientKey: growthbookClientKey,
  enableDevMode: process.env.NODE_ENV === "development",
  subscribeToChanges: true,
  decryptionKey: growthbookDecryptionKey,
  stickyBucketService: new BrowserCookieStickyBucketService({
    jsCookie: Cookies,
  }),
  trackingCallback: (experiment, result) => {
    analytics.track(GA4_EXPERIMENT_VIEW, {
      experiment_id: experiment.key,
      variation_id: result.key,
    });
  },
});

useEffect(() => {
    // Load features async
    let isMounted = true;
    if (isMounted && isReady && (userId || gaClientId)) {
      growthbookClient.setAttributes({
        id: gaClientId,
        clientId: gaClientId,
        url: window.location.href,
        language: pageProps?.language || "en",
        slug: pageProps?.slug || "",
      });
    }

    if (isMounted && isReady) {
      growthbookClient.loadFeatures({ autoRefresh: true });
    }

    return () => {
      isMounted = false;
    };
  }, [isReady, userId, gaClientId]);

See the attached screenshots for the warning and our bigquery data source configuration. we are using

<@U052WVA1MH6>/growthbook-react": "^0.24.0"

SDK Please let me know if you need more information

what attribute are you using for assignment, and what attribute are you using for the experiment report?

The assignment is the anonymous id
