I have had that happen to me - after referring to a friend when she clicked on my referral link it had sent her to an Airbnb ambassador instead. A random person outside our state. An automatic message was generated “hi I’m an Airbnb ambassador and I’m here to help you setup your listing” We disregarded it and continued the listing.
turn out - that airbnb ambassador received my referral bonus, after I did all the work (listing description, house manual, pictures and so on)
id suggest to ask your friend if she clicking on that link it takes them to your profile - or some other page.
