What's Wrong?

What's Wrong?
When a Claude Code /remote-control session hits a cost limit, and no terminal confirmation was issued to pause/wait, the session cannot be resumed from the iOS Claude app once the limit expires. The iOS app shows a flashing activity icon as if the session is alive and processing, but no response is ever returned. The session is frozen in a perpetual loading state with no timeout, error message, or recovery option presented to the user. This is misleading as the UI implies work is in progress when the session is in fact stuck.

Environment:

Claude Code version: 2.1.104
Plan: Max
iOS Claude app version: v1.260402.0 (23983293197)
Device + iOS version: [e.g. iPhone 16, iOS 18.4]
Platform: Anthropic API

What Should Happen?

Expected Behaviour:
After the cost limit resets, the user should be able to resume the /remote-control session from the iOS Claude app, or receive a clear error/notification with a recovery path.

Actual Behaviour:
Session appears alive — activity icon flashes continuously — but no response is ever returned. No terminal pause/wait prompt was ever presented, so the user had no opportunity to intervene before the session became stuck. There is no timeout, no error surfaced, and no way to recover from within the iOS app.
