Confusion about scrolling

I haven't been able to find what the final word on scrolling in Android is. According to the python source code, there is a method scroll. But it doesn't work.

According to the Android docs, there's a thing called UiScrollable. But it doesn't work.

According to the appium docs, there's a thing called TouchActions. But it doesn't work.

driver.execute_script("mobile: scroll", {"direction": 'down', 'element': el})
If you do this, you are told that "the method has not yet been implemented".

So what is the final word on scrolling? That it's completely broken? That scroll is supposed to work, and that there is something wrong with my setup?

Comienza rastreando el método scroll del cliente de Python y compáralo con Android UiScrollable, Appium TouchActions y los puntos de entrada mobile: scroll mencionados en el informe. Reproduce los ejemplos si es posible y documenta qué enfoques de desplazamiento son compatibles, qué falla y si se espera que el método no implementado mencionado aún no esté implementado.
