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.

Same thing here on Catalina 10.15.7 on Cubase 11.0.20

I’ve done the latest Big Sur update and Cubase 11
Got my cc121 out today as I’m concentrating on using Cubase more .
With the latest tools download and using usb and the 12v power supply it’s working great.
I admit when I first run Cubase it didn’t show up, but after a reboot of my iMac it was fine.
