A. 1. Check your internet connection: Ensure you have a stable internet connection, either through Wi-Fi or mobile data. 2. Verify your login credentials: Double-check your username and password for any typos. If you’ve forgotten your password, use the 'Forgot Password' option to reset it. 3. Clear app data: Go to Settings > Apps > EXCEED > Storage > Clear Data. This will reset the app and may resolve login issues.

B. 4. Try logging in from a different device or browser to see if the issue persists. This can help determine if the problem is with the app or your account.
