Hi there! Thanks for reaching out. To make sure I understand correctly: you already have the PolyBuzz app installed on your Windows device, but when you try to type, it still prompts you to download the app again. Is that right?

A little more info would help me guide you better:
- Are you using the PolyBuzz app directly on your Windows device, or are you trying to use it via a web browser (like WebKit)?
- Does this message show up right when you open the app, or only when you try to chat or type?
- Have you recently updated the app or the Windows OS?

Meanwhile, here are some quick steps to troubleshoot this kind of issue on Windows with WebKit:

1. Confirm the app status: Try opening the app directly from your Start menu or desktop shortcut rather than clicking links from a web browser, to avoid confusion between app and web versions.

2. Clear browser cache: Since you mentioned WebKit (browser engine), clear the cache for the browser you’re using. Sometimes stale data causes the app detection to fail.

3. Update the app: Check for any app updates in your usual source (Microsoft Store or from PolyBuzz official sources) and install the latest version.

4. Re-login: Log out of the app and log back in, as session issues can cause this prompt.

5. Check for conflicting versions: If you have multiple PolyBuzz apps or similar AI chat apps installed, try uninstalling the duplicates to avoid detection conflicts.

6. Run as Administrator: Right-click the PolyBuzz app icon and select “Run as administrator”—this can fix permission issues affecting app behavior.

If you could tell me if you’ve tried any of the above or other steps, I can help you dig deeper or escalate as needed.

Looking forward to your update!
