@BAS-Viet-Nam Okay, thank you for the hint. Worked on many sites with these 2 functions without any problems. So I will try it with "Wait while element exists" on this specific site.
Hopefully I don't get in an endless waiting-loop ;)
I don't know if i'm doing something wrong but if i put inside the "Read file" command an resource file path "lines from file" the function doesn't work
Doing so means that there is path to another file inside your original file.
Just use resource anywhere in your code.
