Not switching DarkMode when rendered

[Wolk9]

I use the dropdownpicker in a react native app in combination with native-paper and MD3 Material3 themes.

When switching from dark to light and vice versa everything is switching appropriately execept the dropdownpicker. I have implemented the .setStheme helperfunction, but I wont change directly, not even in a useEffect. Until the first click in the dropdown, the mode switches to the appropriate mode.

How do I invoke a complete render of the dropdown?
