Hi there! I understand you're experiencing trouble adding items to your lists on the Fry's app on your iPhone, while it works fine on your desktop. Let’s work through some steps to get this sorted for you.

First, can you tell me:
- Are you signed into the same Fry’s account on both devices?
- Is the app updated to the latest version on your iPhone?
- Do the items simply not appear after adding, or do you get an error message?

Meanwhile, here’s a straightforward approach to troubleshoot this:

1. Check Internet Connection: Ensure your iPhone has a stable internet connection, as syncing your list requires it.

2. Update the App: Go to the App Store, search for Fry’s, and see if there’s an update available. Sometimes bugs affecting list syncing get fixed in updates.

3. Log Out and Back In: In the Fry’s app, log out of your account, close the app completely, then log back in. This often resolves sync glitches.

4. Restart iPhone: Restart your device, which helps reset temporary software issues.

5. Clear Cache (if available): Some apps let you clear cached data in settings; if Fry’s app has this option, try clearing it.

6. Reinstall the App: If none of the above works, delete the Fry’s app from your iPhone and reinstall it fresh from the App Store.

If the issue persists, it might be related to an account sync or app bug recognized by Fry’s. According to their help resources, sometimes list additions not saving properly can be a known issue they’re working on1.

Try these steps and let me know if you see any improvement or if something specific happens at any point. I’m here to help get this resolved!
