Cubase 8.5.15 / 10.11.3 / Eucon support / Ed, please confirm

I hoped that the latest update will solve my issue, but it didn’t.
I need an answer if the eucon support is still to be done, or my Avid Artist Mix should already work with Cubase 8.5.15 ?
I’ve tested on other software (Logic, Live), and it works fluently, so it’s not the matter of drivers or connection with the unit.

Can someone from Steinberg confirm that it’s still a thing to wait for, or should it be working already and It could be a problem with my setup?
