Where can I find "documentary evidence" for App Store Approval for download PUBLIC Facebook Videos?

Question

I developed an application for iOS that allows you to download public videos from Facebook. The application does not allow the download of copyrighted video. The purpose of the application is the sharing the videos through WhatsApp by using the WhatsApp's API.

I submitted the application to Apple, and the Review Team has reject it reporting the following notes:

8.6 - Apps that include the ability to download music or video content from third party sources (e.g. YouTube, SoundCloud, Vimeo, etc) without explicit authorization from those sources will be rejected

8.6 Details

We found that your app allows users to download music or video content without authorization from the relevant third-party sources.

Next Steps

Please provide documentary evidence of your rights to allow music or video content download from third-party sources. If you do not have the requested permissions, please remove the music or video download functionality from your app.

So, where can I find "documentary evidence" ? I believe that downloading video public and not copyrighted is admissible, the application does not download any videos copyrighted. How to procure the necessary documentation to Apple?

Here is the simple procedure that carries my application:

1. Login via Facebook: The application therefore has the access token.
2. Check the Link: Check if the link refers to a video on Facebook.

3. Download Video: Using Graph Api application gets the source link of the video. If the video is not public or is copyright the application prohibits the download and returns an error. The code I used is :

   -(void)requestToFbWithGraphAPI{
   
   isDownloanding = YES;
   internetReach   = [Reachability reachabilityForInternetConnection];
   wifiReach       = [Reachability reachabilityForLocalWiFi];
   if(([self check:internetReach])||([self check:wifiReach])){
   dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
   
       NSString    *urlString;
       NSString    *token;
       NSURL       *url;
   
       token       = [[FBSDKAccessToken currentAccessToken] tokenString];
       urlString   = [NSString stringWithFormat:@"https://graph.facebook.com/v2.3/%@?access_token=%@", videoId, token];
       NSString *encodedURLString = [urlString stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
       url             = [NSURL URLWithString:encodedURLString];
       NSData* data    = [NSData dataWithContentsOfURL:url];
       if(data != nil){
           [self performSelectorOnMainThread:@selector(handleFbResponse:)
                                  withObject:data waitUntilDone:YES];
           isLastAPrivacyViolation = NO;
       }else{
           dispatch_async(dispatch_get_main_queue(), ^{
               statusLabel.text = NSLocalizedString(@"The privacy of the video set by the\nauthor or the copyright does not allow downloading the video.",nil);
               statusLabel.numberOfLines = 2;
               isLastAPrivacyViolation = YES;
               [UIView animateWithDuration: 1.2
                                     delay: 0
                                   options: (UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction)
                                animations:^{
                                    statusLabel.backgroundColor = [UIColor colorWithRed:231.0/255.0 green:76.0/255.0 blue:60.0/255.0 alpha:1.0];
   
                                    statusLabel.frame = CGRectMake(0, -40, SCREEN_WIDTH, 40*2);
                                }
                                completion:^(BOOL finished) {
                                    [NSTimer scheduledTimerWithTimeInterval: 2.0 target: self
                                                                   selector: @selector(resetFromPrivacyNotAmmitted) userInfo: nil repeats: NO];
                                }
                ];
           });
           isDownloanding = NO;
       }
   });
   }else{
       isDownloanding = NO;
   }
   }
   
   
   -(void)handleFbResponse:(NSData *)responseDataFb {
   
    NSDictionary* json = [NSJSONSerialization
                     JSONObjectWithData:responseDataFb
                     options:kNilOptions error:nil];
   
    urlStringSourceVideo    = [json objectForKey:@"source"];
    descriptionVideo        = [json objectForKey:@"description"];
    urlStringPictureVideo   = [json objectForKey:@"picture"];
   
    NSDictionary *fromDict  = [json objectForKey:@"from"];
    nameVideo               = [fromDict objectForKey:@"name"];
   
    if (urlStringSourceVideo) {
   
   [self downloadVideo];
   }
   
   }
   
   -(void)downloadVideo{
   
   
    statusLabel.text = NSLocalizedString(@"Download Started", nil);
   
       [self showCancelRequestButton];
   
   // Create the request.
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlStringSourceVideo]];
    conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
   
   }

8.6 states in part: "without explicit authorization from those sources will be rejected" meaning you will need to obtain explicit authorization.

Under current US law no copyright notice is required for material to be copyright protected. Thus it follows that explicit permission is required in order to ensure that there is no copyright and/or that usage is permitted.

Documentary evidence would be written permission by the owner to use the material. It is up to the user (you) to obtain this permission. Or there may be information on the site or associated with the material stating what use if any is allowed.

Public availability does not mean that there is no copyright or that the material can be used without permission of the owner.
