CC121 not working with Cubase 11.0.0 build 300

Hello everyone,
I’ve recently installed Cubase Pro 11 (coming from Cubase 7.5)
I downloaded all the latest drivers from the Steinberg website.
I restarted my computer only hooking up my Cubase dongle and CC121 to usb.
As I launch Cubase nothing happens, the cubase ready flashlight keeps flashing.
Do I need to do any additional things within the software of Cubase 11 itself?

Under studio setup (in the studio menu) I click add device and select the ‘Steinberg CC121’ but nothing happens…)

I run on macOS Catalina 10.15.4 with a Macbook Pro with usb-c ports.
And perhaps worth mentioning: everytime I start up Cubase it tells me can’t connect to CoreMidi, please restart. When I push ok, Cubase starts up.
