In an attempt to access a collaborative file, A360 does not show up. What is meant by this is; when file open is selected, there is no option to open A360 under the quick access areas, all that can be seen is documents, desktop and other standard quick access shortcuts under the open popup. Yet no A360, I am logged into my A360 account on Revit and have A360 Desktop installed but all of this is to no avail.
