What's Wrong?

My dispatch thread on the Claude iOS app is permanently stuck in an error loop and I need a server-side reset.

Error message displayed:

"API Error: Usage credits required for 1M context · turn on usage credits at <claude.ai/settings/usage>, or use –model to switch to standard context"

Plan: Claude Max
Device: iPhone (iOS app)

Troubleshooting already attempted:

• Force-quit and reopened the iOS app
• Reinstalled the iOS app
• Logged out and back in
• Toggled Dispatch off and on in settings
• Accessed claude.ai via Safari (works fine, but the Dispatch thread remains stuck)
• Opened Claude Code on Windows PC — working normally with Sonnet 4.6

The Dispatch thread appears to have been initiated with a Max model session using 1M extended context. The thread is now in an unrecoverable loop. Since Dispatch uses a single persistent server-side thread with no client-side state, there is no local file to delete and no self-service reset option in the iOS app.

As documented in that issue: reinstalling the iOS app does not reset state, and there is no 'delete thread' / 'clear history' / 'new Dispatch' UI available.

Requested action:

Please reset or clear my Dispatch thread server-side so I can start a fresh session.

Thank you.
