Hello! I understand that you're experiencing an issue with duplicated songs in your Melodista Music Offline Player, and it crashes when you try to play those duplicates. Let's work together to resolve this issue.

First, could you provide me with a little more detail? For instance:
- How many songs are duplicated?
- Have you recently updated the app or your iPhone’s iOS?
- Have you tried any troubleshooting steps already?

Here are a few initial steps you can start with to potentially fix this issue:

1. Restart the App: Close the Melodista app completely and then reopen it. Sometimes, a simple restart can resolve temporary glitches.

2. Check for App Updates: Ensure that you have the latest version of the Melodista app. You can do this by going to the App Store, searching for Melodista, and looking for any available updates.

3. Clear Duplicate Songs: If possible, try to manually delete the duplicated songs from your library. You can do this by selecting the duplicates and looking for an option to remove them.

4. Reinstall Melodista: If the app is still crashing, uninstalling and then reinstalling Melodista might help. This can reset the app and potentially fix issues with duplicated files.

5. Clear Cache: Depending on how Melodista stores its data, there may be a way to clear the app's cache through your iPhone settings. If you need guidance on finding those settings, just let me know.

If these steps don't resolve the issue, please let me know what you've tried, and we can explore more advanced solutions. Are you satisfied with these steps for now?

Unfortunately, I used every one. I tried to fix the problem with your recommendations, but unfortunately nothing helped. But regarding your questions, yes, I have recently updated my iOS. Could this have had any effect on this situation?

Thank you for the additional information! Yes, sometimes updates to iOS can lead to compatibility issues with certain apps, including Melodista Music Offline Player. It's good to know you’ve already tried some steps, but let’s try a few more options since the previous fixes haven’t worked for you yet.

Here’s what we can do next:

1. Check for Known Issues: Some users have reported problems with offline music apps following iOS updates. You might want to check the official Melodista website or their social media channels to see if they’ve acknowledged similar issues after the latest iOS version. You can also check out their FAQ page for any specific advice related to your problem.

2. Reset Network Settings: Sometimes, resetting network settings can resolve app-related issues. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Keep in mind that this will remove any saved Wi-Fi networks and passwords.

3. Contact Melodista Support: If the issue persists, it might be beneficial to reach out directly to Melodista’s support. They may have more specific insights into any current issues with their app following the latest iOS update.

4. Wait for a Patch: Occasionally, developers release patches for their apps to fix issues caused by new operating system updates. Keeping the app updated regularly can help you get these fixes.

5. Alternative Music Apps: If you find the issue continues and it's affecting your experience significantly, you may also want to explore other offline music apps until a resolution is provided.
