1. Timeout should be removed on the same class (line 32 `extesnion.js`): ```js destroy() { GLib.Source.remove(this._updateId); } ``` In `Indicator` class hold sections in `this._sections` array and: ```js destroy() { this._sections.forEach((section) => section.destroy()); super.destroy(); } ``` Now you can remove line 129-131 `extension.js`. 2. Replace line 132 `extension.js` with: ```js this._session.abort(); ```

Forgot to add `super.destroy()` to the first code block. Please add it to the end of `destroy()` function too: ```js destroy() { GLib.Source.remove(this._updateId); super.destroy(); } ```
