GSDK 1.8 Stream View Broken over USB?

Hello Drone stream view is not working with GSDK 1.8 anymore when connected over USB to Skycontroller3. It works when over drone net. Version 1.7 works fine over USB and drone net. Version 1.8 is able to fetch info including battery info etc, but no video when over USB. Is this a known issue? Any work around possible?

@Jerome

SDK 1.8 is only compatible with the upcoming Drone and Controller firmware that are available in beta for developers , and will be released to general public very soon.

@Jerome Is there a way I can get access to the controller and drone beta firmware? When would it be GA? Do you have a timeframe in mind?
