Remote Access in Pro Portal not working with Public Preview R3.6

When I try to use Remote Access via the Pro Portal, I can connect to the MTR but the image is flashing. I cant seem to have a stable session with the MTR.

The screen will go to black for around 5 seconds, then it shows what is on the screen for less then 1 second.

I tried it on 2 MTR devices that I have in our labo but the issue remains.

When I revert the option for Public Preview back to off, I am able to connect and use Remote Access via the Pro Portal without any issue.

We are using MTRoW and have the latest updates.
