Question: how to use "Apps" (e.g. Azure Boards) with teams-for-linux about teams-for-linux HOT 2 CLOSED

You need to use CTRL + Click. That will give you a dialog like this.

Click allow which would open a small window in the same context. You can login there and it should be fine.

a bit more explanation of why you need ctrl + click. That "tells" the app to open the link into the same context/session we are in the app. What you are seeing is that the app is opening in the browser, and that is starting a new session (as electron/the app/ can't share the session with the browser).

Unfortunately there isn't an easy way currently to decide when to open in the browser and what to open in the app. We do it for a few urls we know, but can't do for each app available, as it really depends on their implementation.
