Hi there! I understand you're seeing the error "Sorry, there was a problem saving your tuning" when trying to save or add new tunings in the Fender Tune app on your iPhone. Let's work through this together to get it fixed.

First, could you tell me if this started happening recently or has it been ongoing for a while? Also, have you tried any steps already, like restarting the app or your phone?

Meanwhile, here’s a step-by-step approach we can try:

1. Check Internet Connection: Saving tunings often requires a stable internet connection. Make sure your iPhone is connected to Wi-Fi or cellular data without interruptions.

2. Restart the App: Close Fender Tune completely (swipe it away from the app switcher) and reopen it. Sometimes, this refreshes the app.

3. Update the App: Make sure you have the latest version of Fender Tune from the App Store. App updates often fix bugs that might cause saving issues.

4. Restart Your iPhone: A simple reboot can clear up temporary glitches affecting app behavior.

5. Check Account Status: If you are logged in, try logging out and logging back in. Also, verify your subscription status if applicable, as some features might be restricted otherwise.

6. Storage Space: Ensure your iPhone has enough free storage, as low space might prevent saving new data.

7. Reinstall the App: If the above steps don’t help, uninstall Fender Tune, then reinstall it from the App Store. This often resolves deeper app issues.

If after all this the problem persists, it may be a server issue or a bug that requires direct support from Fender. I can help you contact support or provide their email for further assistance.

Let me know what you’ve already tried or if you want me to guide you through any of these steps!
