@SnapDragon7410 It will be detected as bot if the website you are automating has bot protection. There will always ways around bot detection just require a bit more effort.

Thank you, very helpful

Hello @sudoxx2
I am using Windows OS 11, Python version is 3.11.4, and Chrome Driver version is 118.
I'm trying to download the csv file to a designated folder, but it doesn't work.
Please check my code below.
Is there a problem with the path?
Could you please help me solve it?
Thanks in advance.
