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.

I realized Teams needed this capability within the first 10 minutes of use. It's a shame such a needed and seemingly basic tab-related feature hasn't been implemented yet.
I have a feeling Microsoft is wanting to have Conversations and File in the same location no matter what channel you are on. If they aren't willing to budget on that, at least let us pick a default tab to view first.
I guess I'll continue to painfully click off the Conversations tab every time I navigate to a channel.
