@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 ;)
@yourfriendkarol Please be more specific on what you are going to achieve. Resources in BAS are very powerful but somewhat limited on the other hand. In total I spent few hours on github trying to understand if using a resource would be good for my this or other problem.
