Claude Duet Not Working
Access problems
Can't see Duet, can't sign in, invite not working.
Alert problems
Silent phone, late briefs, missed updates.
Quality problems
Wrong priorities, stale facts, misread threads.
Claude Duet is a research preview, and Anthropic is upfront that it is not finished. When Claude Duet is not working the way you expect, the cause is usually one of three things: your account is not set up for access, your phone is blocking alerts, or you have hit one of the preview's known limitations.
This page is organized by symptom. Find yours, try the fix, and if you are still stuck, the last section explains how to report it.

Claude Duet access problems
If you cannot see Duet at all, it is almost always eligibility, not a bug.
Not on the waitlist
Fix: join on the official page and wait for an invite. A Pro or Max plan alone does not unlock Duet, and opening a normal Claude chat does nothing. See the waitlist guide.
Wrong plan
Fix: check the account you are signed in to. Free accounts and Team or Enterprise seats are not eligible. If you have more than one Claude account, the invite belongs to only one.
Region
Fix: none for now. The preview is US-only. The availability tracker logs expansion.
Also check you installed the official app from Anthropic. An unrelated third-party app called "Duet" controls Claude Code agents and will not show Claude Duet.
Claude Duet missed alert or update
Between check-ins
Duet checks connected apps every few hours, not continuously, and there is no guaranteed alert time. Anthropic lists missing something that arrives between check-ins as a known limitation. Fix: for anything urgent, ask directly ("check my inbox now for anything from the bank") instead of waiting.
Notifications off
If the work is happening but you are not hearing about it, the phone is the problem. On iPhone, allow notifications and add Duet to your Focus modes. On Android, set battery use to Unrestricted. Full steps are in the iOS and Android guides.
Claude Duet misjudged urgency
Tell it what matters
Anthropic says Duet "can still misjudge what's urgent." Fix: correct it in plain language in the thread, naming the person, project or type of message, and repeat the correction if it recurs. The morning brief guide has ready-made wording.
If Duet keeps acting on old information, for example a meeting date that changed, ask it for a fresh read of that thread before it updates anything.
Claude Duet limitations in the preview
Official list
Anthropic's FAQ answer to "What isn't ready yet?" names three gaps: Duet may misread a thread, miscalibrate urgency, and miss items between check-ins.
No live browser view
You cannot watch Duet's browser while it works. Instead, review its sources and the finished result, and ask in the thread for a list of what it did.
| Symptom | Likely cause | Fix |
|---|---|---|
| Duet missing from app or claude.ai | No invite, wrong account or plan | Check account; join waitlist |
| Brief arrives late or silently | Phone notification or battery settings | Allow notifications; unrestricted battery |
| Something urgent not flagged | Arrived between check-ins | Ask for an immediate check |
| Wrong items at the top | Urgency misjudged | Correct priorities in the thread |
| Uses old facts | Working from an earlier read | Ask for a fresh read |
| Hitting usage limits fast | Background checks and big tasks | Connect fewer apps; stop old follow-ups |
A handed-off task never came back
Big jobs run in the background and report back when they finish, so silence for a while is normal. If a task seems to have vanished, work through these checks.
- Look for a pending approval. The task may be finished except for a step that needs you, such as sending a message. Scroll the thread for a waiting button.
- Ask for status. A plain "where are you on the dashboard?" gets a progress report.
- Check the connected app. If a connector was disconnected or its login expired, the agent cannot read or write there. Reconnect it in your Claude settings.
- Check usage. If your plan hit its limit, background work pauses until it resets.

Feedback
Anthropic asks preview users to help shape Duet, and says it will keep tuning it based on what early users report. If something is not working for a specific task, report the example in the app: what you asked, what it did, and what you expected. Usage problems? See how Duet's usage is counted.
