Remote Control: 'not yet enabled for your account' on Max 5x plan

Bug description

claude remote-control --verbose returns:

Error: Remote Control is not yet enabled for your account.

Environment

• Claude Code version: 2.1.78
• Plan: Max (5x)
• Auth method: OAuth (claude.ai login, not API key)
• Platform: Linux (Ubuntu, 6.14.0-1015-nvidia)
• Rate limit tier: default_claude_max_5x
• Subscription type: max
• OAuth scopes: user:file_upload, user:inference, user:mcp_servers, user:profile, user:sessions:claude_code

Steps to reproduce

1. Authenticate via /login (OAuth, claude.ai)
2. Confirm claude auth status shows loggedIn: true, authMethod: oauth_token, apiProvider: firstParty
3. Run claude remote-control --verbose
4. Error: Remote Control is not yet enabled for your account.

What I've tried

• Re-authenticated via /login (fresh token with updated scopes and expiry confirmed)
• Started a fresh Claude Code session after re-login
• Verified subscription is Max 5x
• Confirmed version 2.1.78 (requirement is ≥2.1.51 per docs)

Expected behavior

Per the Remote Control docs:

Remote Control is available on all plans. Team and Enterprise admins must first enable Claude Code in admin settings.

As a Max plan subscriber (not Team/Enterprise), Remote Control should be available without admin opt-in.

Notes

The error message suggests a server-side feature flag that hasn't been enabled for this account. No additional debug output is shown even with --verbose.
