Hi there! I understand you're able to load the JCPenney app but can't filter items or go to the next page. I want to help get this sorted for you.

Just to clarify first:
- Are you using the JCPenney app on your iPhone or browsing directly on Safari?
- Have you tried filtering or navigating before, or is this a new issue?
- Are you connected to Wi-Fi or using cellular data?

Meanwhile, here are some initial things we can try on your iPhone iOS 18.6.2 to fix this:

1. Close and Relaunch the App:
- Swipe up from the bottom and hold to see apps (or double-click home button), then swipe up the JCPenney app to close it.
- Relaunch the app and try filtering or navigating again.

2. Check for App Update:
- Open the App Store, tap your profile icon, and scroll to see if there's an update for JCPenney. Updating can fix bugs causing issues with filtering or paging.

3. Restart Your iPhone:
- Press and hold the side button and either volume button until the slider appears, slide to power off, then turn it back on.

4. Clear App Cache (If possible):
- Some apps allow clearing cached files under iPhone Settings > JCPenney, but if not, reinstall the app as next step.

5. Reinstall the JCPenney App:
- Delete the app by holding its icon and tapping "Remove App," then reinstall it from the App Store. This often clears corrupted data that causes navigation problems.

If the issue continues after these, could you let me know if it happens over Wi-Fi and cellular data both? Also, do other apps on your phone work fine without navigation issues?

Let me know, and we'll dig deeper if needed! Are you satisfied with trying these steps for now?
