Update of dashboard based on SharePoint file or Onedrive file

Hello,

I have a dashboard based on some csv files, published in PowerBI services.

The first time, my csv files were on OneDrive Enterprise and the second time there were on sharepoint of Office 360 group.

In these two cases, I change a data in a file but in the dasboard the data were still the same, there was no update.

Someone could explain me why please? I thought in Onedrive or Sharepoint data are updated every day.

Thanks
