I've implemented the following for the Photon-Playfab merging. It works in the editor, but in the WebGL build, the callbacks (both) for the method are never executed, and the game gets stuck after. Could it be a potential bug? Thanks a lot for your time!
PlayFabClientAPI.GetPhotonAuthenticationToken(new GetPhotonAuthenticationTokenRequest()
{
PhotonApplicationId = "SOME-HARD-CODED-ID"
}, AuthenticateWithPhoton, DisplayPlayFabError);
