Hi there! I understand you're having trouble logging into the SWISS app on your Android device. To help you better, could you tell me what exactly happens when you try to log in? For example, do you see any error messages, does the app freeze, or does it just not accept your credentials?

Meanwhile, here are some initial steps we can try:

1. Check Your Internet Connection
Make sure your device is connected to a stable Wi-Fi or mobile network.

2. Verify Your Credentials
Double-check your username and password. If you forgot your password, you can reset it here: Forgot your password - SWISS.

3. Clear App Data and Cache
- Go to Settings > Apps > SWISS app
- Tap "Storage"
- Clear Cache and then Clear Data
- Restart the app and try logging in again.

4. Update the App
Ensure you have the latest version of the SWISS app from the Google Play Store.

5. Check Device Time & Date Settings
Incorrect device time can cause login issues. Make sure your date and time are set correctly or set to automatic.

6. Restart Your Device
A simple reboot can sometimes fix unexpected glitches.

If after these steps you still can’t log in, let me know the exact error message you see or the step where it fails, and I can guide you with more targeted troubleshooting.

Are you able to try these suggestions?
