Sorry, but no. My current path is

C:\Users\<user>\Documents

I literally just navigated to my documents folder in a explorer window and copy pasted the path here. I swear I'm not making this up.

I'm pretty sure that these days syncing your documents folder with OneDrive is two separate opt-ins: one to log in to OneDrive at all and one to select whether to sync your libraries.

I am not going to set up a VM just to check this, but I have multiple Windows machines in operation on Win10 and Win11 at home right now and none of them are syncing my libraries. That ranges from five year old Win10 installs to Win11 installs as recent as a couple of months ago.

For the record, I don't think you're crazy either. There's definitely something baked into the install we're doing differently or some version difference or whatever. It's surprisingly hard to suss this out at this point, since there's a fairly complex set of could-backed choices, first time setup choices and maybe even regional changes, I'm not sure. The one interesting, kinda shocking takeaway is how differently our machines can be set up based on probably some checkmark we each set up differently once ages ago or whatever the hell this is.
