I signed up to the free version yesterday and synced all of my facebook photos, however some albums are missing? You can see some of the synced folders below:-
I am guessing that the folder name is preventing that folder from coming down. Windows has issues with periods at the end of folder names. Do you see anything listed in the “not allowed” section of the odrive menu?
If you rename that album to remove that trailing periods, or add a non-period at the end, it should show up.
