Some questions on PoA in the light of Karvy fiasco

Hi
I am facing similar problem.
Easiest registration gets reject.

I have accounts with Zerodha and Motilal Oswal.
Zerodha is primary account through which CDSL Easi registration was done. I added Motilal Oswal successfully - can view holdings.
Subsequently when Motilal account was added for Easiest, it was rejected!!

Any clues how to do it successfully?
