As stated in the last update, the ability to use multiple Teams accounts at the same time is being implemented in stages for Desktop. Faster tenant switching functionality on the Windows client has been rolled out to the public ring fully, and Mac will begin rolling out soon. Work is in progress on cross-tenant notification improvements, and support for multiple accounts on desktop will follow. We’ll keep you posted!
Note: The ability to use multiple Teams accounts at the same time is supported on iOS & Android today.

We are in the process of switching over from Slack to Teams but this is fast becoming a blocker to us adopting Teams across our business. Clients are not happy to switch between tenants and are missing notifications in chats. Can we get the release date please?
