As of yesterday. The mandatory mask wear in public transport and stores in Denmark is gone.

We only have to wear a mask when we go in or out of public transport but when we sit down we can take the mask off (not entirely following the logic here, but hey. Less masks). We still need to stay 2meters from each other, as far as I am aware, but I am currently sitting in a "cramped" metro xD

You can still wear mask and some people want to do so and thats entirely their own decision now.
No one will bat eye if you don't do so.
