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.

Guest access just doesn't work.
(No I do not mean it is impractical. I think it WOULD be impractical. If it worked.)
The Windows Teams Client just logs me in as another user if I switch company.
The Android Client simply crashes, or returns me to the guest company account.

Same thing here.
I added firstname.lastname@example.org as a guest to teams (using @customer.com)
If I login as email@example.com I get the option to switch from mycompany to customer.com
(in the titlebar, next to my picture)
Then, if I switch, Teams suddenly signs in as firstname.lastname@example.org
(an account I use in Outlook)
All this is on my pc.
On my phone, the app just crashes or returns me to mycompany.com
