Thank you @bayomio
Unfortunately, I’ve tried all that. Product condition and brand don’t migrate and I only get one category regardless. Maybe I’m doing something wrong, but no luck.
Some of my other attributes (which I created and works on other plugins with no problem) are not caught by Facebook either. Isn’t there a way to manually map attributes for Facebook other than the option you’ve suggested? I have another plugin (sheet editor) which picks most of Facebook fields, but not brand or product condition. Otherwise I’d change from there.
Thanks.
