What's Wrong?

Title: Dispatch non-functional since 29 March incident — messages marked "Read" but no response delivered, reproducible on desktop directly (Max plan)

Body:

Summary

Dispatch has been non-functional on my account since 29 March, following the incident on 28–29 March (ref q5qk1234v205). One single message successfully returned a response on 4 April; every message before and since has failed. The fix shipped in Claude Desktop 1.1.9493 did not resolve the issue for my account. Behaviour matches existing issues #40178, #40958, and #45937.

Notable:

  • The failure reproduces when typing into Dispatch directly on the macOS app, not only from the paired iOS device — suggests the broken state is at the Dispatch session/agent layer rather than the device pairing bridge.
  • One brief recovery on 4 April (a single successful response, then back to broken) suggests the failure state is transient/recoverable server-side rather than permanently wedged.

Timeline

  • 29 March: Dispatch stopped responding (following 28–29 March incident q5qk1234v205)
  • 4 April: One single message returned a response, then the failure resumed immediately
  • 4 April – present: 100% failure rate across all subsequent messages, ~2 weeks

Environment

  • Plan: Max
  • Hardware: MacBook Pro 14-inch, Apple M5, 16 GB
  • macOS: Tahoe 26.3.1 (a)
  • Claude for Mac: 1.3109.0 (35cbf6)
  • Paired mobile device: iOS Claude app 1.260409.1
  • Pairing status: iOS app shows green "Online" indicator at top of Dispatch thread

Expected behaviour

Messages sent into a Dispatch thread (from either the iOS app or the macOS app directly) should be received by the Dispatch agent, processed, and a response delivered back to the conversation thread on both devices.

Actual behaviour

  • Messages sent from iOS are delivered to the desktop agent and marked as "Read"
  • Messages typed directly into the Dispatch thread on the macOS app produce the same result: no response, stuck on "Read"
  • No response is ever generated or delivered, on either device
  • Thread remains stuck on "Read" indefinitely
  • Behaviour is 100% reproducible on every message attempt, from both devices (with the single exception of one successful message on 4 April)
  • iOS app continues to show green "Online" connection indicator throughout
  • Standard (non-Dispatch) Cowork sessions and Claude Code sessions function normally on the same account, same machine, same network

Steps to reproduce

  1. Open paired Dispatch thread
  2. Send any message — either from iOS app or typed directly into Dispatch on the macOS app
  3. Observe: message shows "Read"; connection indicator remains green
  4. Wait: no response ever arrives

Troubleshooting already completed

  • Updated Claude for Mac to latest version (1.3109.0)
  • Force-quit and relaunched Claude for Mac multiple times
  • Toggled Dispatch off, hard refresh, toggled back on
  • Full logout on both desktop and mobile, re-paired via QR code
  • Confirmed Mac remains awake (lid open, no display sleep) and Claude for Mac stays running throughout
  • Confirmed non-Dispatch Cowork sessions work normally on the same setup — rules out VM provisioning, API reachability, and auth
  • Confirmed the failure reproduces when sending from the macOS Dispatch UI directly — rules out iOS client and device pairing

Impact

Max plan subscriber, Dispatch is a core daily workflow dependency, broken for 3 weeks.
