I am having some problems building a Facebook WebGL product with UnityIAP. If I make my builds through the Build window and Facebook set to WebGL everything works fine. However, if I make my build using BuildPlayer and options set to Target=WebGL and Group=Facebook nothing works.
Am I doing something wrong? Or is this just broken?
