Can't add a new highlight to my Instagram page

Hi

I can successfully add pics and vids by using "create new post", but I can't seem to add a new highlight, to go across the top of the page. I click on "new" and get a field where I can add a highlight name, and I can't do anything with the next window after that. (below).

I am not on a smartphone; is this not possible on a browser? I tried turning off adblock, but that doesn't seem to help. Ideas?

Thanks in advance.

I don't use Instagram nor any other social media so can't help you. I'm not sure you'll find many users here who are. Hopefully one who uses Instagram will read this and have an answer.

In lieu of adding a new highlight to your story, consider to add a new reel of a photo slideshow while praying to the social gods that not all your potential customers have moved to Threads.
