If your Gmail name is not changing, there are several potential reasons that could be causing this issue. Some of the most common reasons include:
1. Google may be experiencing issues: Sometimes, when Google is experiencing technical issues, Gmail updates can be delayed or not work properly. This can result in changes to your account not being reflected for some time.
2. Your Google account settings may be incorrect: If you have not updated your Google account settings or have changed your name in one place but not another, this can cause issues with your Gmail name not changing.
3. Your browser may be caching old data: Cached data in your browser can sometimes prevent changes from appearing immediately. To fix this, try clearing your cache and refreshing your Gmail account.
4. You may have reached a name change limit: Google allows users to change their names a limited number of times. If you have reached this limit, you may need to contact Google support to request a name change.
To resolve this issue, you can try the following steps:
1. Log out of your Gmail account and log back in to see if the changes have taken effect.
2. Check your Google account settings to ensure that your name is updated in all relevant places.
3. Clear your browser cache and cookies, then log back in to your Gmail account.
4. Contact Google support if you believe there may be a technical issue or limit on changing your name.
