Mac OS X (Catalina 10.15.7) firewall blocked MS Teams today (Microsoft Teams Version 1.3.00.362, last updated on 14/10/2020) from sharing the screen, even though the Teams were allowed Screen sharing under the OS X system permissions. I had to turn off the firewall to fix the problem, but this looks like a serious security glitch on the part of MS Teams. Having turned the firewall off, in a matter of minutes I experienced an attack on my computer which was only denied with the help of Norton 360 so that an intruding computer was blocked (i.e., hopefully).
