Blogdown: cannot see latest post in recent posts

I've published my blog to netlify: https://affectionate-allen-e5fa8f.netlify.com

Github: https://github.com/OmarGonD/omargonzalesdiaz

I've created a new post today: 4/26/2019.

I can acces the blog section:

https://affectionate-allen-e5fa8f.netlify.com/blog/

But I cannot see my post. It has the date of today.

Do I need to hardcode this?

Rmd file:

---
title: "react-class-based-components"
author: "omar gonzales diaz"
date: "4/26/2019"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
