It seems that if I press "Run until this" , and there is a Browser Settings operation accross the operations, it will not stop at the desired action but run the script fully.
@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 ;)
