Vercel < > Neon Integration for Branching on Preview Deploys not working (possible bug)

I've been following the official Neon docs to setup the Vercel <> Neon integration, but I'm in a weird state where I am successfully using Neon as my DB in my NextJS app, but I can't setup the preview deploys to automatically create a new db branch. In the integration section on Neon, I see "Manage Neon Subscription" under the vercel integration (see screenshot) But clicking it takes me to Neon settings, which don't have the same options that @mahmoud 's videos show for setting up the integration. It's just taking me to the billing page. Any ideas where to go from here?
