Recent update wiped my whole account, but I'm still getting push notifications for all the holds I can't access! Customer support says "oh well" and recommends that I "back up" my Libby account more often so I don't lose my history (which would do nothing for the lost holds and checkouts on my account). They can't explain the push notifications and won't investigate further. This is honestly a stellar app otherwise, so it's unfortunate that OverDrive could have a bug this huge and not care.
