I can confirm working flawlessly here! I would imagine this is going to be unsupported by either Fourier or UA but - working perfectly on my rack - Very cool. Made my fourier worth twice as much to me because of this.
You need to activate your UAD Plugins in UA-Connect on your online PC or Mac. Within UA-Connect you can transfer your licenses to an iLok.
Transfer your Plugin-Data as in the description above, connect your iLok to the transform.engine and you’re good to go.
