Hi Dr Mark Kent,
To help us narrow this down, could you please provide a few more details?
- What is the exact name of the application you're using? Your post mentions a "Photo designer App," but we're not sure which photo editing application that refers to.
- Does the issue occur with all photos or only specific images?
- Where are the photos stored: on your local PC, an external drive, or cloud storage such as OneDrive?
- When you select Save a copy with a new file name, is the new file created successfully but contains the original unedited image, or do you receive an error message?
- Approximately when did the issue start?
- What is your Windows version?
With those details, we can better determine whether this is an application-specific issue or a problem with how the edited copy is being saved.
