Numbers does not update NSE/BSE stock price updates since 30th March 2021
Why did number stop getting India NSE/BSE stock price updates since 30th March 2021?
Is there alternative available to it in Numbers?

Problems with non-US stock prices has been a common complaint in these forums for several months now.
I recommend you go to Numbers > Provide Numbers Feedback and file a bug report (bug is one of the choices in the dropdown).
Be sure to give as many specifics as you can (e.g., which symbols aren't working for you).
Meanwhile, you could set up a stock list in Google Sheets and copy-paste prices from there into Numbers.
