Blackmagic eGPU and Catalina

Is there a driver or firmware update for the Blackmagic eGPU sold by Apple? Ever since Catalina I am having a problem after the system goes to sleep -- I am able to wake it okay and type in my password but then the display flashes black for a few seconds before it comes back. It operates after that without problems until the next time i have to boot or it goes to sleep.

Hy InMnBob, I have the same problem it look like a bug.
My way are I dont using the button sleep. I was adjusting the time before sleeping mode and my Mac sleeping alone like a kid And the weakeup are simple and efficiency.
Good luck,
