Hello!
I have the following experience on my MTRoW when being invited to a Webex Meeting.
The one button join does not bring me all the way to the Webex meeting but ends half way trough with an error message. There is a small Retry/Cancel popup. Clicking CANCEL gets you to a browser window showing "enter Webex meeting". IF I kno manually enter the meeting id and such, I am able to join.
So it kind of works but NOT with a single button.
Was there any recent changes as I know, that it did work some weeks ago.
