What's Wrong?

When Claude Code calls AskUserQuestion during a remote/web session, the prompt appears inside the mobile app but no push notification is delivered. The user has to manually open the app to discover that input is needed, which defeats the purpose for long-running async tasks.

What Should Happen?

Expected: Push notification fires when the agent is blocked waiting on user input.
Actual: Prompt only visible after opening the app.
