DB Chooser failing in iOS9 - app not allowed to query for scheme

Okay, well I'm not using openURL, I'm using [NSData dataWithContentsOfUrl:file.link] as in the original message - included here again slightly edited. Like I said, this has worked fine until now...

- (void)executeDropboxImport // THIS IS FOR TESTING ONLY - SHOULDN'T NEED IT

{

  NSLog(@">>>> METHOD: executeDropboxImport <<<<<");

  [[DBChooser defaultChooser] openChooserForLinkType:DBChooserLinkTypeDirect fromViewController:self completion:^(NSArray *results) {

    NSLog(@">>>>> Importing after Dropbox selection");

    if ([results count]) {

      // we have a file

      NSLog(@">>>>> Count is greater than zero, so let's import <<<<<");

      NSDictionary *jsonDict = nil;

      DBChooserResult *file = [results firstObject];

      NSString *ext = [file.name pathExtension].uppercaseString;

      NSString *importFile = [NSString stringWithFormat:@"ImportFile.%@", ext];

      NSString *localPath = [NSTemporaryDirectory() stringByAppendingPathComponent:importFile];

      // Make a local copy of the file

      if (file.size > 0 && ([ext isEqualToString:@"JSNST"])) {

        NSData *localFileData = [NSData dataWithContentsOfURL:file.link];

         [localFileData writeToFile:localPath atomically:YES];

        NSError *jsonError;

        NSData *fileData = [NSData dataWithContentsOfFile:localPath];

         jsonDict = [NSJSONSerialization JSONObjectWithData:fileData options:NSJSONReadingMutableContainers error:&jsonError];

        if (jsonError) {

          // error stuff

         } else {

          // do stuff with the data

      }

  }];

}
