Your browser stores a copy of pages it has visited so they load faster. The downside: after a change (for example a widget rebuild), you may still see the old version of the page. There are two ways to be sure you see the latest version:
- Open the page in a private/incognito window, or
- Force a hard refresh in your browser.
Chrome / Edge / Firefox on Windows and Linux
Press Ctrl + F5 (or Ctrl + Shift + R).
Chrome / Firefox / Edge on Mac
Press Cmd + Shift + R.
Safari
Hold Shift and click the reload button, or press Cmd + Option + R.
Brave
Press Ctrl + F5 (or Ctrl + Shift + R).
Why this matters for Proca widgets: after you rebuild a widget, both your webpage and the dashboard Demonstration can show the cached old version.
