A. 1. Reset Password: If you are having trouble signing in, try resetting your password. Use the 'Forgot Password' option on the sign-in screen to receive a reset link via email. 2. Check Internet Connection: Ensure that your device is connected to the internet. A weak or unstable connection can cause sign-in issues.

B. 3. Clear App Data: If the app allows, clear the app data or cache as mentioned earlier. This can resolve issues related to stored login information.
