-# Task: Remove Obscuring Windows from Product Screenshots
+# Task: Fix Screenshot Update Issue
 
 ## Context
 
-The user has reported that screenshots in the "suivi produits" (product tracking) section still contain windows (popups, overlays) that obscure the content. A specific example provided shows a "Stock Inconnu" and "Calendrier de l'Avent" popup on a B&M website.
+The user reports that in the "Suivi prix" (Tracking) section, triggering an update ("Mise à jour") does not update the screenshot. This has been identified as a caching issue due to static filenames.
 
 ## Current Focus
 
-Investigating the scraping and screenshot logic to handle these popups.
+Implementing logic to generate unique timestamped filenames for screenshots to bypass browser caching and ensure the latest image is displayed.
 
 ## Master Plan
 
-- [x] Explore codebase to locate scraping and screenshot logic <!-- id: 0 -->
-- [x] Identify specific handling for B&M or generic popup closing <!-- id: 1 -->
-- [x] Implement fix to close popups before screenshot <!-- id: 2 -->
-- [/] Verify fix (Requires App Rebuild) <!-- id: 3 -->
+- [x] Modify `tracking_scraper_service.py` to use timestamped filenames for tracking screenshots <!-- id: 0 -->
+- [x] Verify that `item_service.py` correctly picks up the new files <!-- id: 1 -->
+- [x] Create verification script `verify_screenshot_update.py` <!-- id: 2 -->
+- [x] Run verification and confirm fix <!-- id: 3 -->
 
 ## Progress Log
 
-- Initialized task.md
-- Created implementation plan to expand popup selectors.
-- Updated `browserless_service.py` with expanded selectors and retry logic.
-- Attempted local verification but failed due to environment restrictions.
+- Identified the issue: `ScraperService` overwrites `item_{id}.png`.
+- Created implementation plan.
