MacOS 10.14.6, RDP 10.6.7 1896 (and earlier and current beta)
I just started having this problem after the last set of updates on my computer. I can connect once to any number of computers with RDP, but once a connection has been disconnected, I cannot reconnect to the lost connection nor connect to any new computers, the connection attempts hang at "Configuring remote PC" Restarting the app does not resolve the issue, I have had to reboot my computer. I do use smart card auth for remotes, I have removed the card and attempted connections, no difference.
Has anyone else run into this?
