MacOS Sierra running the Microsoft Remote Desktop version
8.0.36 application connecting to various different MS Windows servers.
Was working fine, but following the Sierra update 10.12.2 the drives are not mapping, regardless of the target OS.
Current workaround is to use remote desktop in a VM, but this is really inconvenient.

Another Sierra update, another broken RDP client. Microsoft finally updated their RDP client in early January to fix this problem. Now the Sierra 10.12.3 update's come along and broken it. So no drive mappings again.
The beta RDP client has too many problems -- I just need a working RDP client -- so have to resort to using a VM running Windosw and it's RDP client.

Seems that the High Sierra update on my Mac has broken the remote directory sharing again. "Microsoft Remote Desktop" version 8.0.43
Updating the "beta" to version 8.2.41 enables me to connect and the drives are mapped.
Checking the Mac Application Store and they've released a new version of "Remote Desktop" (obligatory skipping of version 9 - why do they hate number nine?); now version 10.1.1. This works
