I'm not sure if it's possible, but it would be really helpful for users who try to check in an OverDrive title they have on Kindle to get an error message other than the general one that says to try again later. Titles that have been sent to Kindle need to be checked in through Amazon. Most of our patrons go through the Libby app, which gives them return instructions there, but we've had a few try to return these titles from their Vega account portal and are confused when they get an error.
