Does Chromebook folder redirection in Horizon 4.1 actually work ?

Prior to 4.1 support for local drive access / redirection for chromebooks was explicitly excluded .

However the chromebook specific doco for the newly released 4.1 has a section on how to implement / utilise drive / folder redirection. Which infers it is now supported.

However when I try  , it all sets up as per the doco ,  no errors etc , however the drive share doesn't show in the VDI view eg the drive is unselectable thus no content can be read.

I was abit worried when I saw the mention of \\tsclient , given a older terminal server type method.

The intent was to have access to a USB memory stick from within the VDI , when accessed via Horizon 4.1 running on Chromebook (chromeOS).

The USB is seen and supported when accessed directly within ChromeOS , and is vsibile for selection in the Horizon App , just not within VDI.

Is this meant to work ? 

Has anyone got it to work ?

Thanks
