Dual winwing MCDU support?

[Eurosky]

I have a dual WinWing MCDU setup. Capt & Fo. With both MCDUs active none of my WinWing products will work. Disabling/unplugging one MCDU and ops normal. 

I contacted WinWing support about this. 

This is the answer I got from WinWing support in regard to dual MCDU support for the A340:

Dear customer, currently due to issues of the Inibuild A340 plane model, we can only support MCDU of Captain side.

Please wait for the plane model manufacturer to update the plane.

Hi. Sorry this is being communicated this way as we have not been notified about needing to do anything special on our side. 
I will ask the team to reach out to WW and see if what they say.

I only have one MCDU so I can't confirm or deny that you can use two units with the 340, but can you confirm that you have one MCDU set to CA and the other set to FO in SimAppPro?

I can confirm that. With both MCDUs connected and correctly configured, none of my Winwing products work (I have pretty much all of them). As soon as I disconnect the FO MCDU, everything comes back to life.

Worth mentioning that everything connected from Winwing works flawlessly on the Fenix A320.
