What's Wrong?

What's Wrong?

In Dispatch, some assistant messages render as a normal chat bubble on all devices, while others render only as a collapsed "Working notes" section on the desktop app — and those "Working notes" messages never appear at all on mobile or tablet clients, even after the conversation is fully synced and marked as read elsewhere.

This defeats a core purpose of Dispatch (checking in remotely from a phone or tablet while away from the desktop), since substantive replies can be silently missed with no indication anything was sent.

I initially suspected this was tied to message length (short one-line acknowledgments synced fine, longer multi-paragraph replies did not), but that theory broke under further testing — a long message synced correctly to all three devices in one instance, while a short message immediately after it failed to reach mobile/tablet. So the pattern appears intermittent rather than a clean rule based on length or content type.

Environment

• Desktop app version: Windows, Claude 1.26832.0 (056ee2) 2026-08-06T05:43:05.000Z (Confirmed latest)
• Mobile OS/app version: Android/ 1.260721.20 (26072120)
• Tablet OS/app version: Android/ 1.260721.20 (26072120)
• Searched is:issue state:open Dispatch (4 pages) and did not find an existing report matching this specific symptom.

Evidence

Three screenshots attached showing the same point in one conversation across desktop, phone, and tablet — desktop shows the full reply inside a collapsed "Working notes" section; phone and tablet show it missing entirely, with only the short surrounding acknowledgment messages present.

What Should Happen?

Expected Behavior

Every assistant message sent to the user should render identically (as a normal, visible chat message) across desktop, mobile, and tablet — regardless of length or content.

Actual Behavior

Some assistant messages are only visible on desktop, collapsed inside a "Working notes" UI element, and never reach mobile or tablet at all.

Error Messages/Logs

No error messages.

Steps to Reproduce

Steps to Reproduce

1. Start a Dispatch conversation and use it across desktop + at least one remote device (phone and/or tablet).
2. Have the assistant send a mix of short acknowledgment messages and longer, multi-paragraph substantive replies.
3. Compare what renders on desktop vs. what actually arrives on the remote device(s).
4. Observe that some longer replies appear only inside a collapsed "Working notes" section on desktop, and are absent entirely from the remote device's chat history — no message, no notification.
