Hi....even for me it shows the same status. I had submitted my application on 19th Jan and completed references on 31st Jan.
since last one week, its showing under review. I don't think any further action is required from our side as all things are submitted.
From the forum replies, I can see, post complete submission, it normally takes 10-11 days for evaluating the initial application and deciding whether to invite for Kira interview.
Let us know if you see any changes in your application status or any further updates.
