Thank You! It works well to set a default category for all newly created ads.
BUT: It seems, that categories of ads cant be changed at all after creation. With or without this JS snippet.....
Are there any more settings in studio/dev needed, to be able to change the category of an ad?
As the ads form depends from the category type (different set of fields for different types) then it would be more easy to create the new ads :-)
