Update 5/2/2018: This issue has been resolved. Thank you for your patience!
RBdigital's account registration feature does not appear to be working currently. RBdigital displays the following error message when users attempt to register for an account: "We are unable to identify you as a patron. Please contact your library for more information."
The account sign in and the rest of the interface seem to be functioning normally.
We have contacted the vendor and will keep you apprised of any updates.
