I have used Microsoft teams got about two years. It can blur my background. That is very good. Their rival, Zoom, can change the background into your own image. That sounds much better. That is very useful, even the background is blurred, but the teammates still can see my room is quite messy. That is better to be completely changed to another image.
But today, I used Teams as my daily routine. It got a new feature. I can change my background now. However, I still cannot find a way to use my image as the background. You can choose from their preset collections of the photo. Well, there are a lot of choices, such as Mindcraft, Office Room, Space station, etc.
In the end, I love this new feature!
