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.

Temporary Fix: Use InPrivate (edge), Private (Firefox) or Incognito (chrome) and you can log into each o365 account without conflicting with the other browser windows. So you can be logged into all 4 at the same time and not have a problem. we do this when we test with multiple user account in the same tenant as well as multiple accounts across multiple tenamnts
