Hi there! I understand you're having trouble signing in to the LiA app and even logging in anonymously. Let's start by getting a bit more detail to help you better.

When you say "unable to sign in," are you encountering any specific error messages? Also, when you try to log in anonymously, what happens—is there an error, or does it simply not allow you to proceed?

In the meantime, here are some general steps that have helped users with LiA login issues in 2023:

1. Remove Existing Leia Accounts: On your Android device, go to Settings > Users and accounts > Accounts, then remove any Leia-related accounts. Sometimes, lingering account data can cause conflicts.1

2. Clear App Cache and Data: Go to Settings > Apps > LiA app > Storage, then clear the cache and data. This can resolve corrupted temporary files.

3. Ensure the Latest Version: Make sure your LiA app is updated to the latest version available in your app store.

4. Check Network Connection: Since login requires internet access, verify your Wi-Fi or mobile data is working properly.

5. Try Reinstalling: If all else fails, uninstall the LiA app, then reinstall it fresh.

If these don’t resolve it or if you see specific errors during login, please share those details with me to narrow things down further.

Are you able to try those steps and let me know how it goes?
