@STripathi Sir, thank for your reply.
The thing is that after entering the UPI id manually, it is not showing "verified". However, he is able to add the funds using the Kite app using the aforementioned UPI id and for IPO application, he is able to receive the mandate after entering the UPI id manually (but it does not show "verified" under UPI id field).
However, my cause of concern is whether the UPI id is considered "valid" for the IPO application or not (since it does not show "verified" under UPI id field after entering it manually).
Request to you and other CG members to shed the light on it.
