No data for Frontend Performance

Hi everyone!

We’re using Sentry 21.8.0.dev0.
I’ve used the following config for our React App:

import * as Sentry from '@sentry/react';
import { Integrations } from '@sentry/tracing';
...
Sentry.init({
  dsn: config.sentryDSN,
  environment: config.env,
  release: process.env.RELEASE_VERSION,
  integrations: [new Integrations.BrowserTracing()],
  tracesSampleRate: 0.5,
});

We also have Sentry.ErrorBoundary and Sentry.withProfiler(App); for our root App component.

We have data on Issues page and for Performance - Transaction but no data about Performance - Frontend:

and also empty Trends and transaction web vitals.

Could anyone please explain why we’re not getting frontend performance info?

Thank you,
Kirill.
