[BUG] Published Claude Code artifacts do not appear in the mobile app (they show on web and desktop)

Problem

Artifacts published from Claude Code get a claude.ai/code/artifact/<id> URL. On the web (claude.ai/code) and in the desktop app they show up fine. The desktop app even lists them in two places: the global Artifacts view and a separate Code artifacts view.

The mobile app does not show them at all. It has a single general Artifacts view, and that view does not include Claude Code artifacts. There is no Code section on mobile.

The artifacts are tied to the account and hosted on Anthropic servers, so the same content should be reachable wherever I am signed in. Showing on web and desktop but not on mobile looks like a consistency problem rather than intended behavior.

Steps to reproduce

1. Publish an artifact from a Claude Code session. It gets a claude.ai/code/artifact/<id> URL.
2. Sign in on the web or desktop app with the same account. The artifact appears in the global Artifacts view and in the Code view.
3. Open the mobile app with the same account and go to the Artifacts view.

Expected

The artifact shows up in the mobile Artifacts view, ideally with the same Code grouping the desktop has, and it opens like it does everywhere else.

Actual

The mobile Artifacts view does not list Claude Code artifacts. With no Code section, there is no way to reach the artifact from the app itself. The only workaround is pasting the claude.ai/code/artifact/<id> URL into a mobile browser.

Notes

Opening that URL in a signed-in mobile browser does work, so this is about listing and discovery in the app, not about access or permissions.

This is close to #75992 but not the same. That request is about rendering files generated during a remote Code session on mobile. This report is about published artifacts missing from the mobile Artifacts list.

Environment

Published from: Claude Code
Shows on: web, desktop app (global and Code views)
Missing on: mobile app Artifacts view (iOS; app version not noted)
