Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

Plan: Pro/Max, account shows signed in on desktop
Phone cannot discover/see the desktop session at all — not just a retry failure, pairing itself isn't happening
No one else on your team/setup has this issue
Already tried: sign out/in (multiple times), full app restart, full machine reboot, clearing the stored auth token in Settings → Claude Code

What Should Happen?

should be able to run /remote-control on desktop code and then be able to see my desktop on my phone app
