Hi there! I understand you're having trouble with items not being added to your cart in the Belk app on your device. Let's get this sorted out together.

To help me guide you better, could you tell me a bit more? For example:
- Are you using the Belk app or browsing on a web browser on your Android 10 device?
- When you try to add items, do you see any error messages or does nothing happen at all?
- Have you tried any steps already to fix this?

In the meantime, I can suggest a few general steps that often resolve this issue:

1. Clear Cache and Cookies: Since you're using an Android device, try clearing the cache and cookies for the Belk app or your browser. Sometimes, stored data causes conflicts that block the cart function.

2. Update the App or Browser: Make sure your Belk app and your browser (if using browser) are updated to the latest version compatible with Android 10. Outdated versions can cause functionality problems.

3. Check Cookies Settings: If you’re browsing, check that your browser’s cookie settings are not blocking cookies from opening. Cookies are small files that help remember your shopping cart sessions.

4. Restart the Device: A simple reboot can refresh your device and close any stalled processes that might be affecting the cart.

If those don’t do the trick, we can dig deeper—like looking into app permissions, checking if you’re logged in properly, or seeing if there’s a glitch specific to your account or device version.

Go ahead and try those initial steps, and let me know how it goes or if anything specific happens when you attempt to add items to your cart. I’m here to help!
