Hi.
This explains why all the non-relevant elements in the struct where set with empty/default values.
From what I have tried and you say, I think I will go through the 'delete-and-reset' way. I will probably use the 'get_cookies_by_attribute' method to know which one to cancel and set a new one again.
As for the regular 'add_event' method I couldn't either figure out how to set the values according to the signature....

Thank you again for the explanations, I'll check-in back with my results.

Regards.
