I don't get into OneDrive too often, but I've found THOUSANDS of duplicate and triplicate files in my 'Photos' folder. Various 'Help' topics indicate I should log into OneDrive, navigate to 'Settings' and 'File Management' (or similar) and manage them from there, but there is nothing remotely related to managing files, backing up, syncing, and so on.
Furthermore, when it suggests going to Microsoft for help, I keep clicking URL's to get to an area, and it repeatedly forces me to log in. (I've done so about three times to get to THIS area.)
Microsoft has gotten EXTREMELY clunky and NOT user friendly. 'Help' is a bunch of worthless AI suggestions. You're nearly as bad as Google's 'suite' of terrible apps.
