Have you read this? 
I know that most people here are not technical but faddat is writing in English over here. I donāt need to explain what heās written since the L1 team will not reply to this also. Itās almost like they can see this and not replying to it cause this puts them in a bad position.
At least according to me, this does not look like good work. In fact, @ek826 you were tasked with managing this team. I havenāt done a review of their work but it sure seems like someone did. And I have a feeling that if all of us reviewed the work, there would be around 100 problems in it.
I highly recommend reviewing this team once again and removing or replacing useless elements in it.
