Snapchat does not notify users when someone removes them from their friends' list. So, if you remove someone as a friend on Snapchat, they will not receive any direct notification informing them of the action.
However, it's important to note that Snapchat is a constantly evolving platform, and the company may have introduced new features or changes .
Also, keep in mind that while Snapchat does not directly notify users when they are removed as a friend, someone might notice they are no longer on your friends' list if they regularly check their friend's list or notice a lack of your updates in their Stories feed. So, in a practical sense, they may still figure it out without receiving a direct notification.
