Hi there! I understand the Hilton Honors app was running very slowly for you before, and now after reinstalling, it won't open at all. Let’s get this sorted out together.

To start, could you let me know if you see any error messages or if the app just stays on a loading screen? Also, is your device connected to a stable internet connection when you try to open the app?

Meanwhile, here’s a step-by-step guide you can follow to troubleshoot this issue on your Android device:

1. Clear Cache and Data:
- Go to Settings > Apps > Hilton Honors.
- Tap on Storage.
- Select Clear Cache first and try opening the app again.
- If that doesn’t help, come back and select Clear Data (this may require you to sign in again).

2. Check for Updates:
- Open Google Play Store.
- Search for Hilton Honors app.
- If there’s an update available, please install it.

3. Restart Your Phone:
- Sometimes a simple restart helps to refresh system resources and fix app issues.

4. Check Permissions:
- Go to Settings > Apps > Hilton Honors > Permissions.
- Ensure the app has permissions enabled for Storage, Location, and Network (if applicable).

5. Network Check:
- Ensure your device has a stable internet connection.
- You might try switching between Wi-Fi and mobile data to see if the app opens.

6. Reinstall Properly:
- Uninstall the Hilton Honors app.
- Restart your phone.
- Reinstall the app from the Google Play Store.

If after trying these steps the app still won’t open, there could be an issue related to your account or a specific version incompatibility on your device. In that case, the next best step would be to reach out to Hilton’s support directly at [email protected] for more specialized assistance.

Let me know how these steps go, or if you notice anything specific such as error messages or freezes—I’m here to help! Are you able to try this now?
