Prototyping not working at all (or is off somehow)

Hi, still learning Figma, but working on a file with my company, and I can’t seem to get prototyping to work.

I am the file owner, and when I go into the prototype tab, and select an element, nothing happens. I don’t get any handles or anything. I’ve confirmed this on Chrome iOS and the Figma app on iOS, and also with another co-worker on their computer.

Any ideas what this could be and what to do? It’s almost as if it’s just turned off for my version of Figma :slight_smile:
