Hi @Lotte Møhl Dyrlund ,
To make sure that the documents on your SharePoint Communication Site are always updated when you change them in your OneDrive folder, use the OneDrive sync app to sync the files between the two locations. This way, any changes you make in one place will be reflected in the other automatically.
Check out the steps in this document or the video:https://support.microsoft.com/en-us/office/sync-sharepoint-files-and-folders-87a96948-4dd7-43e4-aca1-53f3e18bea9b
In normal circumstances, the OneDrive application syncs your files continuously as soon as it detects a change, which it should do automatically. If you are experiencing desynchronization, you can only try "Pause syncing" and then "Resume syncing."
Open OneDrive’s window again, and click or tap on the Pause button from the top.
