Why is it that most "chat/conference" apps become horrible sooner or later? I still remember when teams used to be an OK app. It even had a Linux desktop client. I remember when slack was actually fast, I remember Skype out being more reliable to make phone calls than my mobile/cell service. Today slack is extremely slow if you add few organisations to it (but at least you can add more than one). Teams has deprecated their Linux desktop client and the only way to use it on Linux is via chrome, but wait, if you use it as part of office365/sharepoint you need to use Firefox for "some" sharepoint links. So essentially you need 2 browsers at all times. Chrome for teams (screen sharing and video), Firefox for some sharepoint links.
