Yeah, our daily stand ups are via Teams (international team too) and it works pretty smoothly.
One oddity I’ve noticed is that when working from home and on (fast) Wi-Fi, it will hang for a moment and say the connection has an issue, but then be fine for the rest of the call. When I’m in the office in don’t think I’ve seen it do that.
That was my reaction almost exactly. It’s like Dunning-Kruger the job description.
