Nuendo 13 with Avid S4, joysticks are not working

Hi,
Is anyone using Avid S4/S6 with Nuendo 13?
I worked fine with the S4 joystick in N12, but after upgrading to N13, It just doesn’t work…
Also the MTM doesn’t work if you try to pan with fingers on the screen.
I also found the front/rear pan has change the direction from N12 to N13. Why is that?
I could use custom setup on S4 joystick to control the panning, but the direction is totally opposite for front/rear, as it will move the sound to rear if I move the joystick up;<
Anyone has the same issue?
I was hopping to use space controller OSC app as a substitute, but there is no N13 in the App.
