What's Wrong?

claude remote-control returns "Remote Control is not yet enabled for your account" despite having an active Max plan subscription.

Diagnosis:

• claude --version: 2.1.80
• claude auth status: loggedIn: true, authMethod: oauth_token, apiProvider: firstParty
• ~/.claude.json: hasAvailableSubscription is NOT SET, tengu_ccr_bridge: false in cachedGrowthBookFeatures
• No DISABLE_TELEMETRY or CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC env vars set
• Full logout + re-login (claude auth logout && claude auth login) does not fix it — tengu_ccr_bridge remains false

This appears to be the same server-side feature flag issue reported in #29569, #33119, #34528, #36034.

What Should Happen?

claude remote-control should start a remote control session and display a QR code / URL, as documented for Max plan subscribers.

}

# ~/.claude.json (relevant fields):

cachedGrowthBookFeatures.tengu_ccr_bridge: false

Steps to Reproduce

1. Have an active Max plan subscription
2. claude auth logout && claude auth login (fresh login)
3. claude auth status → confirms loggedIn: true, oauth_token, firstParty
4. claude remote-control → "Error: Remote Control is not yet enabled for your account."
5. Check ~/.claude.json → tengu_ccr_bridge: false, hasAvailableSubscription not set

Same pattern: Max subscriber, tengu_ccr_bridge GrowthBook feature flag returns false server-side, cannot be overridden locally. hasAvailableSubscription is not synced to ~/.claude.json despite active subscription.

Environment: Windows 11 Pro build 26200, Git Bash (mingw64), updated to latest version (2.1.81) — same result.
