Products not showing up in collection page

Good day,

I have the same problem on my website cokoyoga.com . New products dont show up on my collection page on the website.

In the admin page:

  • I checked the collections → the product shows.

  • In the Navigation page → also shows.

  • In the Online store → already published.

This happens like 10 times. Before, I feeel like my products ghosted me. some shows up after 1 day, some never shows up…

So what is my problem please?
