Hi there! I understand you're seeing a white screen when trying to use the OTC Health Solutions app. I'd love to help you get that fixed.

To start, could you tell me if you're experiencing this white screen right after opening the app, after logging in, or during some specific action within the app? Also, have you tried any troubleshooting steps so far, like restarting the app or clearing cache?

Meanwhile, here are some common first steps that often resolve white screen issues in apps:

1. Force close the app and reopen it: On Windows with WebKit (like browsers), simply close the browser tab or window completely, then open it again.

2. Clear your browser cache and cookies: Sometimes cached data can interfere with how the app loads. Go to your browser settings, find Privacy or History, and clear your browsing data (make sure to clear cache and cookies).

3. Try disabling any browser extensions or pop-up blockers: Extensions sometimes block app scripts that the OTC app needs to run properly.

4. Ensure your Windows 10 is up to date: System updates can help prevent compatibility issues.

Could you please try these steps and let me know if the problem persists? If so, I'll guide you through some deeper troubleshooting next.
