I am a member of both these libraries and I am having difficulty returning ebooks before their due date.
I have my borrowing period set to 21 days (incase lots of my waitlisted books appear at once and it takes me longer to read them) but as I finish a book I do like to return it immediately so that others can borrow it.
I return the book on both my Kobo and in ADE and I know that it has worked previously but at the moment the books are staying "borrowed" according to the library even though they are no longer on my Kobo or in ADE.
I have sent an enquiry to the library itself but I wondered if anyone else has any ideas.
Thanks
