When can we use File Transfer on SfB for Mac version?

Hello,

I am an Office 365 business user in China. The China version of 365 (operated by China 21Vianet) still no plan for Teams migration.

We have to use Skype for Business on Mac computers. But the Mac version of SfB is very low. There is no File Transfer, no Screen Capture and no Screen Control functions.

Please update SfB for Mac. Thank you very much indeed.
