As far as I understood, Cisco changed the name of Webex-Teams to "Webex" - perhaps to avoid confusion with MS-Teams.
The "classic" Webex is now more clearly named Webex-Meetings.
The features of Webex(-Teams) and Webex-Meetings are still very much the same as the have been before.
Based on what we all "feel", Cisco seems to work on merging those products into one single Tool.
But this is still in progress - there are still some differences between Webex(-Teams) and Webex-Meetings.
Because of that I think it´s best practise to keep both Clients installed and updated.
