We do have a workspace one portal and it gives this same error when trying to launch virtual apps/desktops on a chromebook.  They do run in the web, but I suspect the performance would be better in the client.  The difficulty is that I can manage the chromebooks, but I have no administrative access to our portal.  would it be possible to link the appropriate documentation?  I'm not having any luck finding it, and since I don't have access I need to forward it to one of the Workspace one administrators anyway.
