Project Online, Project Sites Document Library synchronization button is gone

Iron Contributor

Since last week we discovered that on all document libraries in the modern view, within our PWA site collection of SharePoint Online, the synchronization button is gone.


We created a Microsoft Support ticket and they simply responded that the disabled it, in the modern view of doc libraries on site collections which are PWA enabled. Only the classic view enables a user to sync a document library.


Anyone expierencing this too?

I cannot believe MS just made this change when its something thats key to working with document libraries in our environment.


They werent able to give me a reason as of why its been removed.

Hi Randy,

While I'm surprised of the reply to your service ticket, this is a bug that can also be found in your O365 Admin center, see attachment.
