Why is github pages not updating?

Question

GitHub

There is a repository, there is a react application. This repository is configured as github pages, it works when you go to a certain url.
The only catch is that I decided to add one library to the project, made a commit, made a push. If you look at the code of the repository, then it has changed. I open this project through github pages (I enter the required URL in the address bar) - everything is the same there. 2 hours passed.
How to treat it? Maybe change something in the repository settings?

As far as I remember, they blunt. Sometimes for hours. And even until the day. It helped me to wait.
