Pinning unsynched folders in File Manager

I seem to be able to pin synched folders. But it will not let me pin unsynched folders.

Is this a “feature” or am I missing something?

Can you clarify what you mean by Pin?

Are you talking about the Windows ability to pin folders to the taskbar? If so, unsync folders are actually placeholder files, and not folders. If you want to pin them you would want to sync the cloudf so that it turns into a physical folder. You can still leave everything else inside of it unsynced.
