In continuation to this question, I am now able to use ShazamKit in my app, but for every video I pass to it didFailWithSignature is always called: func session(_ session: SHSession,        didNotFindMatchFor signature: SHSignature,                  error: Error?) {         DispatchQueue.main.async {             print("match error: \(String(describing: error))")         }     } with the following output: match error: nil This is happening even with videos that are just screen recorded video clips of Ed Sheeran for example, something that Shazam would easily recognized. Any idea why that would happen? What I should investigate? (the full code is also updated on my GitHub
