Bug Description

Technically not a bug with Claude Code, but it seems Anthropic is blocking Claude Code from accessing shared conversations on claude.ai:

● Fetch(https://claude.ai/share/afca1707-a8cd-403d-8c0b-0d97ce6be2ff)

I don't know where else to report this.

2. Tell Claude Code to fetch it.

Expected Behavior

Claude Code will fetch the conversation.

Actual Behavior
