Preview was Feb 2019. Its now almost December and 10 months later and the MACOS has been updated twice in the time frame and and still no release of teams for Safari. My guess is that this is extremely unimportant and will never see the light of day. Guess its to use the actual app instead of a browser. Extremely disappointing that this will not be supported but I guess that is what happens. Simply use a different option than teams I guess if you want to use MACOS and a browser.
