To resolve the login issue you are experiencing with LemFi, particularly related to WebView, follow these detailed steps:

1. Check App Permissions: Ensure that your LemFi app has the necessary permissions to run. Navigate to your device settings, find the LemFi app in the list, and verify that all relevant permissions (such as Network Access) are granted.

2. Clear App Cache: Sometimes cached data can cause problems like failed logins. Go to your device settings, then the 'Apps' section. Find LemFi, tap on it, then access the 'Storage' section. Here, select 'Clear Cache'.

3. Update the App: An outdated app may lead to various issues. Ensure that you have the latest version of the LemFi app installed. Visit the app store on your device and check for updates.

4. Reboot Your Device: A simple reboot can resolve many technical glitches, including WebView issues. Restart your device and then attempt to log in again.

5. Reinstall the App: If the problem persists, consider uninstalling and then reinstalling the LemFi app. This can help fix any underlying issues due to corrupted installation files.

6. Use a Different Login Method: If possible, try using an email/password login instead of Google or other third-party services, or vice versa. This method can sometimes bypass WebView issues.

7. Check Internet Connection: Make sure your device is connected to the internet. Poor connectivity can lead to login failures. Switch between Wi-Fi and mobile data to see if that resolves the issue.

8. Enable WebView: Ensure that WebView is enabled on your device. In your device settings, go to 'Apps', look for 'Android System WebView', and confirm it is enabled.
