I managed to find a temporary workaround until this is fixed:

• Remove the value prop from the <RNPickerSelect />
• Use a ref (<RNPickerSelect ref={picker} ... />) and set the initial value (using setState) at the beginning:

  
  const picker = useRef<RNPickerSelect>(null);

useEffect(() => { picker.current?.setState({ selectedItem: { label: 'Example B', value: 1 } }); }, []);

Please note that the full item (including label) needs to be passed, not only the value.
