Why shivangi joshi is leaving yrkkh?

I think she left because the show is doing a big jump in time. They call it a generation leap. So, the story of her character, Naira and then Sirat, is finished now. Her part of the story is complete. The show makers wanted to start a fresh story. This new story is about the next generation of kids. So they needed new actors. It was not because of any fight or problem. It was just the plan for the show to move forward. I will miss her and Mohsin Khan on the show very much.
