Missing photos Description in Photos after Graph Request

My App is a C# .NET App

For many years, I have been retrieving a list of photos stored in a published OneDrive folder for my Photo Dia app via Graph Request. The request URL: https://graph.microsoft.com/beta/me/drive/items/IDItemFolder/children

I previously received:

I was able to fill in the Title field in Windows Explorer, and it was displayed under Description in OneDrive.

When I copy a file that still exists, this feature is no longer synced when syncing with OneDrive. It is displayed in Windows Explorer, but it is no longer visible online and is no longer transferred after the request. Can anyone tell me if something has changed?

My app imports photos for a slideshow, and I used the description feature to display the description for the photo. Now none of my photos have a description anymore. Is there another feature I can use to save my photo descriptions, which I can then retrieve with the Graph Request URL?

Thanks

Peter
