Hi! I’m Grace Wilson. I see you’re getting an error message when trying to log in to the Marcus app. I’d be happy to help you get this sorted out.

To start, could you tell me exactly what the error message says? That can help me pinpoint the issue more accurately.

Meanwhile, here are some initial steps you can try that often clear up login problems:

1. Clear your browser’s cache and cookies. Sometimes old or corrupted data can cause login errors.
2. Try logging in using a different browser or updating your current browser to the latest version.
3. Check your internet connection. If you’re on Wi-Fi, try switching to mobile data or vice versa.
4. If you have a PIN or password involved, ensure you’re using the correct credentials and try resetting your password if you’re unsure.
5. Make sure you’re logging in within the valid time window if a temporary PIN is provided—for instance, within 15 minutes after receiving it.

If you’ve tried these steps already, please let me know which ones so we can explore deeper troubleshooting tailored for your Windows device and WebKit browser.

Does this help so far? What is the exact error message you’re seeing when you try to log in?
