UIDocumentPickerViewController directoryURL no longer opening correct folder

Since iOS 18, I have gotten user reports that the UIDocumentPickerViewController directoryURL is no longer opening the correct folder. Instead it is just loading the root directory of the Files app/iCloud files.

Did something change in iOS 18 that I need to account for? Not all users are having this issue, but some are and they are frustrated because a major feature of my app was to allow users to save files at the ubiquityURL.

I use the following to get the path:

NSURL *rootDirectory = [[[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil] URLByAppendingPathComponent:[NSString stringWithFormat:@"Documents/Photos/%@", folderName]];

Is there something that I need to do differently now in iOS 18 to prevent this from happening?
