I have just taken a song, transposed it from F to A and then saved it in one of my song books. On re-opening my songbook I do have the transposed version there, so it is working fine for me. Any editing that is wanted or required can then be performed in the songbook
Yes there is a new server and there have been some behind the scenes changes to the way that Chordie works which has presented a bug or two but they seem to be ironed out now.
