Hi team. is this a acceptable practice to use multiple useFeature in a page ?
Copy code
const Sample: React.FC = () => {
  const feature1 = useFeature('feature1');
  const feature2 = useFeature('feature2');

  return (
    <>
      <Button color={feature.value || 'blue'}>feature1</Button>
      <Button color={feature.value || 'blue'}>feature2</Button>
    </>
  );
};

export default Sample;
And also do we get experiment for multiple a/b testings in trackingCallback: async (experiment, result) ?

the trackingCallback gets called once for each feature.

Thanks, so can I expect two logs in the following code ? ( with enabled namespaces )
Copy code
trackingCallback: async (experiment, result) => {
    console.log(experiment, '<<<<<');
  },
I only see one log for the two experiment:

You could expect two logs if both features are in a test. I suspect an A/B test was not set up for one of them.

you may also want to check the FAQ for when the tracking callback gets called as it isn't called in all cases: https://docs.growthbook.io/faq#why-is-the-trackingcallback-not-firing-in-the-sdk
