Why it takes long times to update aadhar
Currently all the services are working slow because of less staff and many other issues due to covid-19 pandemic. You can contact your near-by Aadhar kendra to update any information or you can also direct update information through their official website by providing valid documents.

Feel free to comment if you have any doubt
Good luck
