Hello! I understand you're having trouble adding music to your album in the eSound app on your iPhone with iOS 18.5. Could you tell me a bit more about what exactly happens when you try to add the music? Do you see any error message or code besides "try again"? And does this happen for all songs or just specific ones?

Meanwhile, I can guide you through some initial checks and steps:

1. Check Internet Connection: Make sure your iPhone is connected to a stable internet connection (Wi-Fi or cellular).

2. Restart the App: Completely close the eSound app from the app switcher, then reopen it.

3. Update the App: Check whether there's an update for eSound in the App Store, as bugs sometimes get fixed in updates.

4. Re-login: Try logging out of your eSound account, then log back in to refresh your session.

5. Clear App Cache (if available): Some apps have a setting in their app options to clear cache or temporary files, which can resolve glitches.

If you've tried these already, please let me know, and we can try some deeper troubleshooting. Sometimes, this issue might be related to a temporary server problem or app bug.

Also, I found some reports of similar issues with playlist additions giving errors (like error WC014), which users resolved by restarting the app or waiting for server fixes1 4.

Do you see any specific error code when you try to add music? Let me know!
