Why are the shares credited for an IPO bid not visible on Kite even after receiving confirmation from CDSL?

The confirmation email received from CDSL is only to inform that shares are being credited to the demat account. The shares will only reflect in Kite after they are listed. If the shares have been allotted, they will be credited to the demat account before the listing date, but the stock price will be displayed as NA on the listing day until it is determined.
