We know you are patiently waiting for this feature. This feature is being implemented in stages. Fast tenant switching is currently in testing both internally and with early customers. We expect to release to the public in the Fall. I’ll post an update once it’s rolling out.
Full multi-tenant, multi-user support will be added after fast tenant switching.
As a Microsoft Partner that regularly signs up small businesses to Office 365, we use Teams to enable our clients to communicate with our support engineers. This typically means we have a user in each client's tenant that they can use to get ahold of us as needed. Cannot stress it strongly enough that being able to be logged into multiple Teams accounts at the same time, like we can with Outlook is critical.

Why the Android app is not feature equivalent to the iOS app is beyond me. The iOS and Windows apps can screen share but the Android app is not capable.
