  <p>photonServiceSettings file is missing from photon lib.. although I have a bunch of files related.. this is why I got the error.</p>
  
  <p>Tried to integrate the unique ID from <a href="https://www.photonengine.com/en-US/Photon" rel="nofollow noreferrer">https://www.photonengine.com/en-US/Photon</a> into my unity project.
  Tried to install/reinstall photon (last version September 2019) with no success, cannot advance my multiplayer project because of this. </p>
