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?

Beginne damit, die scroll-Methode des Python-Clients nachzuverfolgen und sie mit Android UiScrollable, Appium TouchActions und den im Bericht erwähnten Einstiegspunkten mobile: scroll zu vergleichen. Reproduziere die Beispiele nach Möglichkeit und dokumentiere, welche Scroll-Ansätze unterstützt werden, was fehlschlägt und ob die gemeldete nicht implementierte Methode erwartungsgemäß ist.
