The error icon shows (I think that's is, the red exclamation point next to "New Folder"), but putting mouse over it/clicking it doesn't do anything. No tooltips show and there's no way to see what it stumbled on.
After clicking "Sync now" for a folder, nothing shows up, even after 25/30 min. Not sure how long the syncing takes. A progress bar would be nice.
My contacts didn't sync either. Not sure if I'm supposed to manually tell it to (can't find a option to do it?).
