If you see a prompt to refresh the page or a blank screen after a Zenamu update, it's most likely caused by your browser cache. Here's how to fix it.
Quick fix
Press Ctrl + Shift + R (Windows) or Cmd + Shift + R (Mac) — this forces a page reload without cache.
If that doesn't help, open Zenamu in a private/incognito window (Ctrl + Shift + N in Chrome).
If the problem persists
Open Browser Settings → Privacy and Security → Clear Browsing Data.
Check Cached images and files.
Click Clear data.
Reopen app.zenamu.com.
Tip: If your clients or instructors report the same issue, send them this article. In most cases, Ctrl + Shift + R resolves it.
Issue with the mobile app
In most cases, removing the app from your home screen and reinstalling it will fix the problem. For a detailed guide, see Mobile App.
