I don't see the new Epicgames name, what should I do?

I just changed my name on the official website of the developer Epicgames. The new name is not displayed in Fortnite despite restarting. Instead, the normal gamertag on my Xbox. Does anyone know how I see the Epicgames name in Fortnite? I've also asked friends if they can at least see this - they can't. I thank you in advance.

May take a while. And try to change the name again as a test. If it says that the name has recently been changed, it has adopted the new name.

Thank you for your answer. It says on me that I can change it again in 2 weeks. Let's hope that it will still be displayed😇😛
