This one is a deal breaker for me. I was migrated to teams this weekend and I'm hoping I can roll back somehow.
I'm an external contractor and my office 365 account is external to the organizations I work with. People used to call me and ask for help and desktop share. Now it doesn't work and it's just causing all of us frustration.
Screen sharing on Chrome and Chromium-based Edge is now supported. We also have released support for joining meetings from Safari, Firefox and IE browsers, with some limitations.

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.
