Works in unity editor but not in build

Hi! I'm using Photon Voice 2 together with an already existing PUN 2 project. I get voice when running it in the editor, but when I build the project I get the following error in the development build: [PhotonVoiceNetwork singleton PhotonVoiceNetwork] Settings are null [PhotonVoiceNetwork singleton PhotonVoiceNetwork] Connecting to server failed I have a voice network, recorder in the scene and a photon voice view + speaker on a player prefab.
