Microsoft Teams Rooms update 18.104.22.168 has been available since earlier this week (as noted previously, we first release to 10% of devices and then increase coverage to 100% in the following days). Current coverage as of April 10th is 10%. [April 15th Update: 22.214.171.124 is now available to 100% of devices.] [April 21st Update: For those IT Managers creating device images, 126.96.36.199 MSI is now available when you run the CreateSRSMedia script.]
This update fixes an issue with the "give feedback" feature that had been reported in a couple of scenarios. 188.8.131.52 also includes optimizations in preparation for the forthcoming MTR device upgrade to Windows 10 Version 1809 (we're working on confirming a release date - thanks again for everyone's patience - we're eager to get the OS upgrade released, too!).
