You can change or update your personal data in the "Profile management" section.

In the mobile version you need to enter the menu "More → Your name and status → Personal details".

When changing your personal details, you may be asked for a photo of the main page of your passport. After creating a request to change your personal data, you should wait for the request to be processed. You should not recreate requests for personal data change, as this will increase the waiting time.
