Hi there! I see you’re experiencing an issue where the Vertilinc Resident app is showing a white screen with just a black dot. Let’s work together to get that fixed.

To start, could you tell me:
- When did this issue begin? Was it after an update or any changes?
- Have you tried restarting the app or your device?
- Are you using the app on your Windows 10 device’s browser or a dedicated app?
- Any other symptoms or error messages showing up?

Meanwhile, here are some basic steps to try and resolve this:

1. Restart the App and Device: Close the Vertilinc Resident app fully, then restart your Windows device. This can clear temporary glitches.

2. Clear Browser Cache (if using browser-based app): Since your device uses WebKit browsing on Windows 10, clear your browser cache and cookies to refresh the app loading.

3. Check Internet Connection: Make sure your network is stable. Sometimes a weak or fluctuating connection causes the app to fail loading properly.

4. Update Software: Ensure your Windows 10 and browser are updated to the latest versions for best compatibility.

5. Try Another Browser or Device: If possible, check if the app shows the same issue on another device or browser. This helps isolate if the issue is device-specific.

If the white screen with black dot persists after these, let me know. I can guide you further into more advanced steps such as checking graphics drivers or app reinstall if applicable.

Does this make sense so far? Any information you provide will help me tailor the solution better!
