Just so you know you are not alone... I'm Cloudflare's CTO and that happens to me. We are working on it :-)

Edit: It's fixed and I'm on the waitlist.

Update: It got sorted out for me and I got my waitlist number after trying again. Now the top banner just shows me my waitlist number.

Happened to me as well, and that’s why I came looking for the canonical post on this topic to see what’s happening. I switched networks and tried, but got no waitlist number. There’s just a message saying I’m on the waitlist and the button to join the waitlist is still visible and enabled.

Now that I see people from Cloudflare have responded, I’ll just wait and see.

Sorry about that, there's an issue we're currently dealing with which hits people who had a specific version of the old 1.1.1.1 app and just updated. It should be fixed shortly.
