1 To give and take control of shared content during sharing, both parties must be using the Teams desktop client. Control isn't supported when either party is running Teams in a browser. This is due to a technical limitation that we're planning to fix.
2 Teams meetings on browsers are limited to a single stream; either incoming video feed of the current speaker or screen sharing.
3 Edge RS2 or later doesn't support sending real-time audio and video traffic through HTTP proxies.
Note
Running Teams in a browser is supported on PCs and Macs that meet the minimum Hardware requirements for Microsoft Teams. For example, running Firefox on the Linux operating system is an option for using Teams.
On mobile devices we recommend that you use the Teams app. The Teams app is available from the Android and iOS stores.
