Last week I wrote about the new Teams Powershell module. 2.3.0 and at that time my advice was that do not install it It's kind of looked that Microsoft "killed" direct Routing.
Yesterday, they came out with a new version. The 2.3.1 and they listened.
According to this link: https://www.linkedin.com/pulse/microsoft-release-fix-microsoftteams-module-v231-elazar-ohayon/?trackingId=noNU3nzxRRKk%2BrpWym%2BqIQ%3D%3D
and I have tested it my self, and now we are back on track.
