I was finishing up my Facebook Ads Training: How to Build Great Ads & Audiences course today but got stuck at Creating a Lead Ad exercise - I have filled in all information but this came up with Invalid Parameter: https://prnt.sc/q15n6w - I have tried to reload the page, restart the exercise multiple times but nothing seems to work. How do I resolve this?
Just to note - I want to create a test campaign instead of a real one as I don't have the need to create a properly running one right now, but I really want to complete the course.
