Specifically, the seen_user_count is reset to 0 for each item in user_list inside the loop, which means it will always be either 0 or 1 and never accumulate across iterations. This effectively makes the threshold check with seen_user_threshold meaningless. @kenpyfin

                if cur_row_height < row_height:

                        "Next item not found: probably reached end of the screen.",
                        extra={"color": f"{Fore.GREEN}"},
                    )
                    break

                username = user_name_view.get_text()
                screen_iterated_followings.append(username)
                # check if a username has seen previously
                if username in seen_users:
                    seen_user_count += 1
                seen_users.add(username)

Corected

you should put seen_user_count = 0 before the while True: loop

I have uploaded the corrected code :)

When scrolling down the following list, if you reach the end and continue to scroll, it shows the following users from the beginning but only one or two at the bottom of the page. The user_list variable gives you all usernames in the visible screen. So seen_user_count will have value more than 1. The reason I put the seen_user_countinside theuser_list ` loop is to prevent occasional "half way" scroll that leaves 1 or 2 previous shown username in the viewable screen and cause early exit of the action.

That's my understanding of the code.
