ChatGPT can read TradingView pages but cannot click, navigate, or switch tabs. Reinstalling ChatGPT, the Chrome extension, and reconnecting CDP only restores control temporarily. The session reports: “Invalid signature (code or signature have been modified).”

What is the expected behavior?
ChatGPT should maintain a stable connection to the Chrome extension and be able to click buttons, navigate pages, open and switch tabs, and interact with TradingView without repeatedly losing browser-control access.
