IPO mandate authorised on UPI but mandate is still pending on Angel One App

I have applied for Happy Forgings Ltd IPO and I have also given the mandate through UPI. Yet, my Angel One app shows please approve your mandate sent to your UPI app. I have already received the confirmation message regarding the acceptance of mandate and the amount is blocked in my account for autopay debit. This is the third time happening to me on Angel One App. Kindly Help.
Please note that my Client ID is : V404191
Please note that today by 05:00 pm the mandate will expire.
