MobileLibrary - Scroll Keywords not working

Greetings,

I started working in a web app and doing some automation, keywords seems to work fine except Scroll (Scroll Up, Down, Into View…)
Getting error:
InvalidArgumentException: Message: Both strategy and selector arguments must be provided

And with Scroll keyword when I put the element well it’s not found…

I want to know if anyone faced this issue and what’s the best way to scroll otherwise (maybe by execute script) I tried Execute Script window.scrollTo(0, document.body.scrollHeight);
but not working: UnknownMethodException: Message: Method is not implemented

BR,
