Hi! Sorry to hear the Let's Roam app isn't opening on your Android device. I want to help get it running smoothly. Just to clarify first: when you tap the app icon, does it do nothing at all, or does it try to open and then crash or close immediately? Also, have you tried any troubleshooting steps already, such as restarting your phone or reinstalling the app?

Meanwhile, I'll suggest some basic steps tailored for your Android 10 device to try out:

1. Restart your phone: This clears temporary glitches that might affect app launches.
2. Clear the app cache and data:
- Go to Settings > Apps > Let's Roam.
- Tap Storage.
- Tap Clear Cache, then Clear Data.
3. Update the app: Check the Google Play Store to ensure you have the latest version installed.
4. Reinstall the app: Uninstall Let's Roam, then reinstall it fresh from the Play Store.
5. Check your internet connection: Sometimes, connectivity issues prevent the app from opening properly.
6. Free up storage if your device is low on space, as this can affect app performance.

If none of these help, there could be a deeper issue such as compatibility or a corrupted install. Let me know what you experience at each step, and we can go deeper if needed. Are you able to try some of these now?
