Hi there! I understand you're facing an error message when trying to log in to the Michigan Lottery app on your Android 10 device using WebKit browser. Could you tell me a bit more about the exact error you see? For example, is it about wrong password, server issues, or something else? Knowing this will help me guide you better.

Meanwhile, here are some common steps that usually help resolve login issues with the Michigan Lottery app:

1. Make sure the app is updated: Sometimes older app versions cause login problems. Head to the Google Play Store and check if there’s an update available for the Michigan Lottery app.

2. Clear app cache and data:
- Go to your device’s Settings.
- Tap on Apps or Application Manager.
- Find Michigan Lottery app in the list and select it.
- Tap "Storage."
- Tap "Clear Cache" first and try logging in again.
- If that doesn’t work, try "Clear Data" (note: this will log you out and reset app settings).

3. Check internet connection: Ensure your network is stable. Try switching between Wi-Fi and mobile data to see if login works on one of them.

4. Verify your login credentials: If you’re getting a message about incorrect email or password, try the "Forgot Password?" option on the login screen to reset your password carefully using your registered email.

5. Reinstall the app: If none of the above works, uninstall the app completely and reinstall it fresh from the Play Store. This can fix corrupted app files.

If you have already tried some of these steps, let me know which ones so I don't repeat them. Also, if you can share the precise error message you’re seeing, I can provide more targeted help.

Would you like me to walk you through any of these steps? Or do you have more details about the error?
