Hi there! I understand that you're having trouble with the cello feature in Perfect Piano, which you paid to add. Let's work together to resolve that.

To get started, could you let me know what exactly happens when you try to access or use the cello sound? For instance, do you see any error messages, or is it just not playing sound? Additionally, when was the last time it worked properly for you? These details will help me understand the issue better.

It says that Prrfect piano requires access to external storage for files

Thanks for the clarification! The message about requiring access to external storage is likely related to the app's need to save or access certain files, such as MIDI files, to provide you with a fuller experience, including the cello sound you paid for.

Here's how to enable permissions for Perfect Piano, so it can access your external storage:

1. Open Settings on your Android device.
2. Scroll down and select "Apps" or "Application Manager."
3. Find and tap on "Perfect Piano" from the list of apps.
4. Tap on "Permissions."
5. You should see a list of permissions. Look for "Storage" and ensure it's set to "Allow."
6. If it’s not allowed, please tap the toggle to allow access.

After you've adjusted these settings, restart the Perfect Piano app and check if the cello feature is working again.

If you're still having trouble after that, please let me know, and we can explore additional solutions together! Are you satisfied with this solution?
