I don't see any other influencers, big or small, with a portfolio in their highlights. The ones I've worked with in the past have a media kit to give to brands when they're approached/approach them.
It sounds like she's really struggling to get brand deals like she used to so she's trying to show off her highlights. Anna and smaller influencers are getting the impressive brand deals and she's getting smaller ones, which unfortunately don't suit her style (making her seem desperate) or bring in the money like Waitrose does. Perhaps if she spent less time moaning and more time focusing on upping her game and making content people actually WANT to see, she wouldn't be struggling so much. But of course, its because she's a mum, never her fault.
