Hi,
i got this error when using WebGl only , my game works fine with no errors (standalone PC Build) , but when i use WebGl build and test i got this :
InvalidCastException: Cannot cast from source type to destination type.
NetworkingPeer.AlmostEquals (System.Object one, System.Object two) (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:4567)
NetworkingPeer.DeltaCompressionWrite (System.Object[] previousContent, System.Object[] currentContent) (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:4416)
NetworkingPeer.OnSerializeWrite (.PhotonView view) (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:4302)
NetworkingPeer.RunViewUpdate () (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:4118)
PhotonHandler.Update () (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/PhotonHandler.cs:165)

    i solved this problemby changing the two lines at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:(4566 , 4567) :
    from 
    float a = (float)one;
float b = (float)two;
    to 
    float a = Convert.ToSingle(one);
float b = Convert.ToSingle(two);

    Hi @AhmedGoba, @Sonicboomcolt,

    Thank you for choosing Photon and your contribution!
    (sorry for the delay)

    Could you help me investigate and reproduce this?

    Does this still happen with PUN1 versions higher than 1.91?
    Does this happen with PUN2?
    On which Unity version can you reproduce this?
    Does this happen inside Unity Editor or only in a WebGL build?

    Could you share minimal repro steps?
