We have a GCC tenant and use G3 licenses for our users. We included the install of Teams with Office365 1908 at the end of March for our Teams rollout. I have yet to see a new version come through. If I manually check for an update it claims I'm at the latest version. That version is 1.3.00.4461 (64-bit). It was last updated on 3/23/20.
Reading about how Teams is updates it sounds like updates can be pushed out every 2 weeks.
What am I missing here?
