Yes - I was going to suggest dropping the group, for a while, if not enjoying it.
Take her to the park as much as you can (weather permitting!) and look at trees, birds, animals, and there should be plenty of flowers opening now. When our DS was little he loved to watch a little stream that ran nearby.
What dolls, teddies, toys etc has she got? Share activities with her, also Duplo, shape-sorting and large-piece jigsaw puzzles. Not TO MUCH screen time, but if watching TV, share it with her, talk about things, characters, settings, etc.
Read to her a lot, share books with her, show her the pictures, and let her handle board-books or textured books. Don't have too many electronic toys that need batteries (bad for the environment, and they make nasty noises!)
Pull-along toys are good; attach a very long piece of cord, and pass it around a secure table or chair. Then, as she pulls the cord, the toy will go AWAY from her. Let her listen to SUITABLE music, and join in with 'domestic percussion' (pans and wooden spoon), or buy her bells, tambourine, little drum, etc.
