We use Teams at work and when you choose the icon it takes you to a screen that has a large icon of a door with a rope in front of it. From there you get to choose Teams on web or Teams the app. The point of the door is to tell you that Teams classic is no longer available, which is a huge part of the visual hierarchy. It's very strange - Teams classic was phased out long ago, but they still tell you this, and the negative connotation of a door with a rope in front of it resides in your mind as you move forward. This is one of the many operating quirks one sees from day to day.
