What's Wrong?

My paid Pro subscription has been rendered completely unusable for the 4th/5th consecutive day due to a catastrophic synchronization loop between the Windows Desktop App and the cloud backend.

Today, June 7, my account was locked out after ONLY 15 MINUTES of minimal manual usage.

The issue triggers immediately when using the Windows Desktop Application. The moment the chat context involves technical infrastructure setups or local tool executions (PowerShell commands, MCP server configurations, unzipping local packages), the Desktop App forcefully locks my profile under the "limits shared with Claude Code" tier.

An invisible background tracking loop instantly drives my session quota to 100% used. I am then hit with a massive 3 to 4-hour session lockout (demanding a 3h 43m wait time today), despite my overall Weekly Limit being at only 51%.

This backend corruption bleeds into the Web Interface (Chrome) as well, throwing "Conversation not found" errors and completely freezing the profile across all devices, treating a paid Pro subscription as a restricted free tier.

What Should Happen?

Paid Pro users should not have their manual chat sessions exhausted in 15 minutes by background tool execution loops.

Error Messages/Logs

Usage limit reached • Resets in 3 hr 43 min • limits shared with Claude Code
Background UI error: "The request may have expired or you may have read it elsewhere. Refresh the page to continue."

Steps to Reproduce

1. Log into a paid Pro Account on the Windows Desktop App.
2. Open a project chat and engage in conversations regarding backend server environments or local tool execution (PowerShell / MCP configurations).
3. Observe how the app automatically flags the session with "limits shared with Claude Code".
4. After less than 15 minutes of standard use, the session is forcefully terminated at 100% capacity, and a 3-4 hour lockout is enforced.
