Hi @LI Laurence
As far as I know, there may not be any other function in Excel can act like "Track Changes(Legacy)".
Based on my research, with a function named version history, you can view older versions of your files stored in OneDrive or SharePoint while AutoSave turned on.
For detailed information, you may refer to this article: Restore a previous version of a file stored in OneDrive.
Hope the information is helpful to you.
