Hi there! I understand you're having trouble signing in to the Express Scripts app and that you've already notified their support team but haven't seen the issue resolved yet. Let’s see if I can help you get back in.

First, could you tell me a bit more about the problem? For example:
- Are you seeing any error messages when you try to sign in?
- Are you using the app or a browser on your Windows 10 device?
- Have you tried resetting your password using the "Forgot Password" option?
- Are you facing any issues with two-step verification or single-use codes?

Knowing these details will help me guide you better. Meanwhile, here are some general steps to try if you haven’t already:

1. Clear your browser cache and cookies (if using a browser to log in). Sometimes cached data can cause login problems.
2. Try a different browser to check if the issue is browser-specific.
3. Use the “Forgot Password” feature on the Express Scripts login page to reset your credentials if you suspect they might be incorrect or outdated.
4. If two-step verification is enabled, be sure to delete any previous verification codes and request a new code; sometimes the codes expire or don’t work if too many are generated.
5. Make sure your app is updated to the latest version if you’re using the mobile app.

If none of these help, you might want to contact their direct web support line at (800) 711-5672 for more specific assistance, especially if the issue might be with their authentication system.

Let me know what steps you've tried and any error messages you’re seeing, and I’ll help you troubleshoot further!

Are you able to share those details?

HAD TO CHANGE E-MAIL ADDRESS AND WHEN I REQUEST A LOG IN THE SCREEN DOES NOT ALLOWTO USE IT IT GOES DARK AND CAN NOT ACCEPT ANY TYPING KEYS

Thanks for sharing those details! It sounds like when you try to log in with your new email, the Express Scripts login screen goes dark and won’t let you type or interact. This kind of “screen going dark” issue can happen due to cached data conflicts, browser compatibility issues, or two-step verification glitches.

Since you mentioned you're on a Windows 10 device with a WebKit browser, let's start with a few targeted steps:

1. Clear your browser cache and cookies: This will remove any stored data that might be interfering with the login page loading properly. You can usually do this from your browser’s settings under Privacy or History.

2. Try a different browser: If you’re using a WebKit-based browser, try switching to Microsoft Edge or Google Chrome. Sometimes the app or site behaves differently depending on the browser.

3. Restart the browser and device: Close all browser windows fully, then restart your PC to clear any lingering issues.

4. Check for two-step verification conflicts: Since you changed your email, the two-step verification might still be linked to your old email. If possible, try logging in to the Express Scripts account recovery page to update your email or disable two-step verification temporarily5.

5. Use the Express Scripts account recovery page: Visit the recovery page directly at https://www.express-scripts.com/recover to reset your login credentials or update your email associated with the account3.

If after these steps, the login screen still goes dark and remains unresponsive, it may be a platform or server-side issue that Express Scripts needs to address. At that point, I would recommend contacting their support again with these specifics—mentioning the dark screen and your email change—to escalate the problem.

Would you like me to guide you through clearing your browser cache or trying a different browser now? Or is there a specific step you want to try first?
