I am having the exact same problem as la_maison_productions. I have set up a songbook that now contains 32 songs but it still says in brackets that is only has 13. When I try to delete a song I have decided I don't want anymore, I get the same "You are not authorised to make any changes to this songbook!" error. I only have one account and one songbook so I can't understand why I am not authorized to made edits to my songbook.
I access Chordie on multiple devices and am having the same problem on my iphone, ipad and PC.
Any suggestions would be appreciated?
