Thanks for following our suggestion to vote this up on SharePoint. It worked! SharePoint has confirmed that they have already started working on this and I’ll be getting an ETA from them after the holidays. -Suphatra
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.

We have fast tenant switching on ios devices, but when will it come for desktop versions?
We are still considering this feature for future releases, and will continue to update the status when it changes.
