How can I synchronize my highlights and comments in the same ADE book on multiple devices?

They don't seem to be reflected automatically.

I don't know of any way that ADE can do this automatically.  It should; but there is a lot else it should fix as well.

You could try checking where the different devices put their Annotations directories and synnc them some other way;

I'm not sure if all the devices will store them in the same format, though.
