I have a MacBook Pro running High Sierra 10.13.6 and Webex meetings 40.2.12.18 desktop app. I have recently been unable to get Webex to work when I "Go to Meeting". I get a spinning wheel and a message that it is having problems accessing the network. I have numerous other Apps that can access the net and the browser version of Webex works. I have tried re-installing the app to no avail. Has anyone else encounter this?
