Will new value from useGrowthbookGetFeatureValue hook triggers App component re-rendering? In case of 'yes' do we need then part with setting state in useEffect?
I mean could you please check, will it work without

     const [dtrader_v2_enabled_gb, setDTraderV2EnabledGb] = React.useState(false);

    React.useEffect(() => {
        setDTraderV2EnabledGb(Boolean(dtrader_v2_enabled));
        // eslint-disable-next-line react-hooks/exhaustive-deps
    }, [dtrader_v2_enabled, Analytics?.getInstances?.().ab?.GrowthBook.getFeatures()]);
