Repeating scroll down doesn't work

[iamhch]

Hi, I need your help.
I wanted to automate the process of scrolling to the bottom and inserting text because there's a long list in the application.
While exploring the scroll functionality, I found something called "simulate scroll wheel down," so I tried using it.
This function takes values in pixel units, and I couldn't input a value greater than 999, so I used 988 and repeated it twice.

Initially, when I started, the scrolling worked twice. However, when it's inside a repeating loop, instead of scrolling twice, it only scrolls once. What could be the issue in this situation?

Hi and welcome to the forum!

The easiest way to go to the bottom of a page is to simulate the End key.

Thank you. but, page down or end key doesn't work in the application. that's why I try to adopt scroll down function.

Which app is it?

@iamhch

page down or end key doesn't work in the application.

Command + Down Arrow also does not work?

[iamhch]

it's whatsapp that I want to automate the process.
page down or cmd+down arrow key doesn't work in chatroom list.
In chatroom list, only scroll down/up or ctl+shift+tap (previous chatroom) and ctl+tap (next chatroom) key work.
That's why I tried dealing with scroll down action.

I'm not sure what's going on with your setup, but this works in the Whatsapp desktop mac app for me:

As does this:

However, these only work if the message area has been clicked beforehand:

Thank you so much for your help.
You're right, Repeating scroll down is working.
I just found my fault in next step "Move and Click and Drag"
Because of Drag to pointx, pointy, the focus is lost so the action of scroll was weird.
I fixed it, repeating scroll down worked.
I really appreciate your kind effort
