This Progressive Web App (PWA) relies heavily on both Service Worker cache and Browser cache to deliver a seamless offline experience.
Please be aware:
- Clearing your browser cache will remove essential files (JavaScript, CSS, HTML) cached by the browser.
- While the Service Worker manages its own cache (Cache Storage), clearing the browser cache can cause some assets to become temporarily unavailable.
- This may result in errors or prevent the app from working properly when offline.
- For the best offline experience, avoid clearing the browser cache while using this app.
- When updates are made, the app uses cache versioning and prompts users to refresh, ensuring you always have the latest version.
If you experience issues after clearing your browser cache, try refreshing the page or reopening the app with an active internet connection.
Thank you for understanding!
